Abstract

Abstract The β-glucosidase gene from Aspergillus nidulans FGSC A4 was cloned and overexpressed in the A. nidulans A773. The resulting purified β-glucosidase, named AnGH3, is a monomeric enzyme with a molecular weight of approximately 80 kDa, as confirmed by SDS-PAGE. Circular dichroism further validated its unique canonical barrel fold (β/α), a feature also observed in the 3D homology model of AnGH3. The most striking aspect of this recombinant enzyme is its robustness, as it retained 100% activity after 24 h of incubation at 45 and 50 ºC and pH 6.0. Even at 55 °C, it maintained 72% of its enzymatic activity after 6 h of incubation at the same pH. The kinetic parameters Vmax, KM, and Kcat/KM for ρ-nitrophenyl-β-D-glucopyranoside (ρNPG) and cellobiose were also determined. Using ρNPG, the enzyme demonstrated a Vmax of 212 U mg − 1, KM of 0.0607 mmol L − 1, and Kcat/KM of 4521 mmol L − 1 s − 1 when incubated at pH 6.0 and 65 °C. The KM, Vmax, and Kcat/KM using cellobiose were 2.7 mmol L − 1, 57 U mg − 1, and 27 mmol –1 s − 1, respectively. AnGH3 activity was significantly enhanced by xylose and ethanol at concentrations up to 1.5 mol L − 1 and 25%, respectively. Even in challenging conditions, at 65 °C and pH 6.0, the enzyme maintained its activity, retaining 100% and 70% of its initial activity in the presence of 200 mmol L − 1 furfural and 5-hydroxymethylfurfural (HMF), respectively. The potential of this enzyme was further demonstrated by its application in the saccharification of the forage grass Panicum maximum, where it led to a 48% increase in glucose release after 24 h. These unique characteristics, including high catalytic performance, good thermal stability in hydrolysis temperature, and tolerance to elevated concentrations of ethanol, D-xylose, furfural, and HMF, position this recombinant enzyme as a promising tool in the hydrolysis of lignocellulosic biomass as part of an efficient multi-enzyme cocktail, thereby opening new avenues in the field of biotechnology and enzymology.

Abstract

Purpose: Within the Solve-RD project (https://solve-rd.eu/), the European Reference Network for Intellectual disability, TeleHealth, Autism and Congenital Anomalies aimed to investigate whether a reanalysis of exomes from unsolved cases based on ClinVar annotations could establish additional diagnoses. We present the results of the "ClinVar low-hanging fruit" reanalysis, reasons for the failure of previous analyses, and lessons learned. Methods: Data from the first 3576 exomes (1522 probands and 2054 relatives) collected from European Reference Network for Intellectual disability, TeleHealth, Autism and Congenital Anomalies was reanalyzed by the Solve-RD consortium by evaluating for the presence of single-nucleotide variant, and small insertions and deletions already reported as (likely) pathogenic in ClinVar. Variants were filtered according to frequency, genotype, and mode of inheritance and reinterpreted. Results: We identified causal variants in 59 cases (3.9%), 50 of them also raised by other approaches and 9 leading to new diagnoses, highlighting interpretation challenges: variants in genes not known to be involved in human disease at the time of the first analysis, misleading genotypes, or variants undetected by local pipelines (variants in off-target regions, low quality filters, low allelic balance, or high frequency). Conclusion: The "ClinVar low-hanging fruit" analysis represents an effective, fast, and easy approach to recover causal variants from exome sequencing data, herewith contributing to the reduction of the diagnostic deadlock. The Solve-RD project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement number 779257. Data were analyzed using the RD-Connect Genome-Phenome Analysis Platform, which received funding from the EU projects RD-Connect, Solve-RD, and European Joint Programme on Rare Diseases (grant numbers FP7 305444, H2020 779257, H2020 825575), Instituto de Salud Carlos III (grant numbers PT13/0001/0044, PT17/0009/0019; Instituto Nacional de Bioinformática), and ELIXIR Implementation Studies. The collaborations in this study were facilitated by the European Reference Network for Intellectual disability, TeleHealth, Autism and Congenital Anomalies, one of the 24 European Reference Networks approved by the European Reference Network Board of Member States, cofunded by the European Commission. This project was supported by the Czech Ministry of Health (number 00064203) and by the Czech Ministry of Education, Youth and Sports (number - LM2018132) to M.M. Sí

Abstract

Xylooligosaccharides (XOS) are widely used in the food industry as prebiotic components. XOS with high purity are required for practical prebiotic function and other biological benefits, such as antioxidant and inflammatory properties. In this work, we immobilized the recombinant endo-1,4-β-xylanase of Malbranchea pulchella (MpXyn10) in various chemical supports and evaluated its potential to produce xylooligosaccharides (XOS) from hydrothermal liquor of eucalyptus wood chips. Values >90% of immobilization yields were achieved from amino-activated supports for 120 min. The highest recovery values were found on Purolite (142%) and MANAE-MpXyn10 (137%) derivatives, which maintained more than 90% residual activity for 24 h at 70 °C, while the free-MpXyn10 maintained only 11%. In addition, active MpXyn10 derivatives were stable in the range of pH 4.0–6.0 and the presence of the furfural and HMF compounds. MpXyn10 derivatives were tested to produce XOS from xylan of various sources. Maximum values were observed for birchwood xylan at 8.6 mg mL−1 and wheat arabinoxylan at 8.9 mg mL−1, using Purolite-MpXyn10. Its derivative was also successfully applied in the hydrolysis of soluble xylan present in hydrothermal liquor, with 0.9 mg mL−1 of XOS after 3 h at 50 °C. This derivative maintained more than 80% XOS yield after six cycles of the assay. The results obtained provide a basis for the application of immobilized MpXyn10 to produce XOS with high purity and other high-value-added products in the lignocellulosic biorefinery field., The authors gratefully acknowledge FAPESP (São Paulo Research Foundation, grants No: 2018/07522-6) and FCT (POCI-01-0145-FEDER-032206)—transnational cooperation project EcoTech, and National Institute of Science and Technology of Bioethanol, INCT, CNPq 465319/2014-9/FAPESP n ◦ 2014/50884- 5) for financial support.

Abstract

A commercial and very hydrophobic styrene-divinylbenzene matrix, MCI GEL® CHP20P, has been compared to octyl-Sepharose® beads as support to immobilize three different enzymes: lipases from Thermomyces lanuginosus (TLL) and from Rhizomucor miehie (RML) and Lecitase® Ultra, a commercial artificial phospholipase. The immobilization mechanism on both supports was similar: interfacial activation of the enzymes versus the hydrophobic surface of the supports. Immobilization rate and loading capacity is much higher using MCI GEL® CHP20P compared to octyl-Sepharose® (87.2 mg protein/g of support using TLL, 310 mg/g using RML and 180 mg/g using Lecitase® Ultra). The thermal stability of all new preparations is much lower than that of the standard octyl-Sepharose® immobilized preparations, while the opposite occurs when the inactivations were performed in the presence of organic co-solvents. Regarding the hydrolytic activities, the results were strongly dependent on the substrate and pH of measurement. Octyl-Sepharose® immobilized enzymes were more active versus p-NPB than the enzymes immobilized on MCI GEL® CHP20P, while RML became 700-fold less active versus methyl phenylacetate. Thus, the immobilization of a lipase on this matrix needs to be empirically evaluated, since it may present very positive effects in some cases while in other cases it may have very negative ones.

Abstract

Endoglucanases (EC 3.2.1.4) are important enzymes involved in the hydrolysis of cellulose, acting randomly in the β-1,4-glycosidic bonds present in the amorphous regions of the polysaccharide chain. These biocatalysts have been classified into 14 glycosyl hydrolase (GH) families. The GH7 family is of particular interest since it may act on a broad range of substrates, including cellulose, β-glucan, and xylan, an attractive feature for biotechnological applications, especially in the renewable energy field. In the current work, a gene from the thermophilic fungus Thermothielavioides terrestris, encoding an endoglucanase GH7 (TtCel7B), was cloned in the secretion vector pEXPYR and transformed into the high-protein-producing strain Aspergillus nidulans A773. Purified TtCel7B has a molecular weight of approximately 66 kDa, evidenced by SDS-PAGE. Circular dichroism confirmed the high β-strand content consistent with the canonical GH7 family β-jellyroll fold, also observed in the 3D homology model of TtCel7B. Biochemical characterization assays showed that TtCel7B was active over a wide range of pH values (3.5–7.0) and temperatures (45–70 °C), with the highest activity at pH 4.0 and 65 °C. TtCel7B also was stable over a wide range of pH values (3.5–9.0), maintaining more than 80% of its activity after 24 h. The KM and Vmax values in low-viscosity carboxymethylcellulose were 9.3 mg mL−1 and 2.5 × 104 U mg−1, respectively. The results obtained in this work provide a basis for the development of applications of recombinant TtCel7B in the renewable energy field.

Abstract

Two different heterofunctional octyl-amino supports have been prepared using ethylenediamine and hexylendiamine (OCEDA and OCHDA) and utilized to immobilize five lipases (lipases A (CALA) and B (CALB) from Candida antarctica, lipases from Thermomyces lanuginosus (TLL), from Rhizomucor miehei (RML) and from Candida rugosa (CRL) and the phospholipase Lecitase Ultra (LU). Using pH 5 and 50 mM sodium acetate, the immobilizations proceeded via interfacial activation on the octyl layer, after some ionic bridges were established. These supports did not release enzyme when incubated at Triton X-100 concentrations that released all enzyme molecules from the octyl support. The octyl support produced significant enzyme hyperactivation, except for CALB. However, the activities of the immobilized enzymes were usually slightly higher using the new supports than the octyl ones. Thermal and solvent stabilities of LU and TLL were significantly improved compared to the OC counterparts, while in the other enzymes the stability decreased in most cases (depending on the pH value). As a general rule, OCEDA had lower negative effects on the stability of the immobilized enzymes than OCHDA and while in solvent inactivation the enzyme molecules remained attached to the support using the new supports and were released using monofunctional octyl supports, in thermal inactivations this only occurred in certain cases.

Abstract

The real and virtual photon emission during interactions between few-nucleon systems have been investigated at KVI with a 190 MeV proton beam. Here I discuss the results of the proton-proton system and proton-deuteron capture. Predictions of a fully-relativistic microscopic-model of the NN interaction are discussed. For the virtual photon processes, the nucleonic electromagnetic response functions were obtained for the first time and are compared to model predictions.

Abstract

A brief introductory survey of γ-ray detector arrays and in-beam electron spectrometers developed during the last three lustra is followed by a broad discussion of the general requirements for single and multiple in-beam e-γ spectrometers. A detailed analysis is made of a few important tools for reducing the low-energy electron background (i.e. simultaneous E-Bp selection, true and random coincidence rates, EM static fields around the target region). This survey and discussion are illustrated by the results of several in-beam e-γ measurements dealing with nuclear spectroscopic investigations of a few medium and heavy nuclei. © 1999 Elsevier Science B.V.

Abstract

A few accelerated ion beam requirements for in-beam e-γ spectroscopy are briefly reviewed as well as several features of the MP Tandem accelerator of IPN-Orsay and the accelerated ion-beam transport devices leading to the experimental area of in-beam e-γ spectroscopy. In particular, the main capabilities of the ion-sources, the ion pulsing system, the ion stripping and stabilizing devices as well as the versatility of the ion beam transport system are discussed from the point of view of the different kinds of in-beam e-γ experiments performed in that area. © 1998 Elsevier Science B.V.

Abstract

The main features of nuclear targets, recoil ion catchers and reaction chambers used in nuclear spectroscopic investigations involving in-beam multi-e-γ spectrometers are discussed. The relative importance of the δ-ray background due to the accelerated ion-target and the recoil-ion-target interaction is estimated. Its impact on the prompt low-energy electron measurements is stressed. Finally a few general features of the interplay between accelerated ion beams, targets and recoil ion catchers particularly relevant for these measurements are broadly discussed and illustrated with typical examples of in-beam e-γ studies. © 1998 Elsevier Science B.

Abstract

Lecitase Ultra has been covalently immobilized on cyanogen bromide cross-linked 4% agarose (CNBr) beads, maintaining 70% of the initial activity. The activity of the immobilized enzyme was improved in the presence of Triton X-100, sodium dodecyl sulfate (SDS), and cetyltrimethyl ammonium bromide (CTAB) (e.g., up to 800% when using CTAB). However, CTAB and Triton X-100 presented a negative effect on enzyme stability even at low concentrations, and SDS cannot be used for a long time at 1% concentration. To maintain the hyperactivated conformation of the enzyme in the absence of detergent, ionic polymers were added during incubation of the immobilized enzyme in the presence of detergents. Coating the immobilized enzyme with polyethylenimine in aqueous buffer (PEI) produced a 3-fold increase in enzyme activity. However, in the presence of 0.1% SDS (v/v), this coating produced a 50-fold increase in enzyme activity. Using PEI and 0.01% (v/v) CTAB, the Lecitase activity decreased to 10%. Using irreversible inhibitors, it could be shown that the PEI/SDS-CNBr-Lecitase preparation allowed its catalytic Ser to be more accessible to the reaction medium than the unmodified CNBr-Lecitase.

Abstract

A commercial and very hydrophobic styrene-divinylbenzene matrix, MCI GEL® CHP20P, has been compared to octyl-Sepharose®beads as support to immobilize three different enzymes: lipases from Thermomyces lanuginosus (TLL) and from Rhizomucor miehie (RML) and Lecitase®Ultra, a commercial artificial phospholipase. The immobilization mechanism on both supports was similar: interfacial activation of the enzymes versus the hydrophobic surface of the supports. Immobilization rate and loading capacity is much higher using MCI GEL®CHP20P compared to octyl-Sepharose®(87.2 mg protein/g of support using TLL, 310 mg/g using RML and 180 mg/g using Lecitase® Ultra). The thermal stability of all new preparations is much lower than that of the standard octyl-Sepharose®immobilized preparations, while the opposite occurs when the inactivations were performed in the presence of organic co-solvents. Regarding the hydrolytic activities, the results were strongly dependent on the substrate and pH of measurement. Octyl-Sepharose®immobilized enzymes were more active versus p-NPB than the enzymes immobilized on MCI GEL®CHP20P, while RML became 700-fold less active versus methyl phenylacetate. Thus, the immobilization of a lipase on this matrix needs to be empirically evaluated, since it may present very positive effects in some cases while in other cases it may have very negative ones.

Abstract

Item does not contain fulltext TSPEAR variants cause autosomal recessive ectodermal dysplasia (ARED) 14. The function of TSPEAR is unknown. The clinical features, the mutation spectrum, and the underlying mechanisms of ARED14 are poorly understood. Combining data from new and previously published individuals established that ARED14 is primarily characterized by dental anomalies such as conical tooth cusps and hypodontia, like those seen in individuals with WNT10A-related odontoonychodermal dysplasia. AlphaFold-predicted structure-based analysis showed that most of the pathogenic TSPEAR missense variants likely destabilize the β-propeller of the protein. Analysis of 100000 Genomes Project (100KGP) data revealed multiple founder TSPEAR variants across different populations. Mutational and recombination clock analyses demonstrated that non-Finnish European founder variants likely originated around the end of the last ice age, a period of major climatic transition. Analysis of gnomAD data showed that the non-Finnish European population TSPEAR gene-carrier rate is ∼1/140, making it one of the commonest AREDs. Phylogenetic and AlphaFold structural analyses showed that TSPEAR is an ortholog of drosophila Closca, an extracellular matrix-dependent signaling regulator. We, therefore, hypothesized that TSPEAR could have a role in enamel knot, a structure that coordinates patterning of developing tooth cusps. Analysis of mouse single-cell RNA sequencing (scRNA-seq) data revealed highly restricted expression of Tspear in clusters representing enamel knots. A tspeara (-/-);tspearb (-/-) double-knockout zebrafish model recapitulated the clinical features of ARED14 and fin regeneration abnormalities of wnt10a knockout fish, thus suggesting interaction between tspear and wnt10a. In summary, we provide insights into the role of TSPEAR in ectodermal development and the evolutionary history, epidemiology, mechanisms, and consequences of its loss of function variants.

Abstract

Correction to: Solving patients with rare diseases through programmatic reanalysis of genome-phenome data. Eur J Hum Genet. 2021 Sep;29(9):1466-1469. doi: 10.1038/s41431-021-00934-6. PMID: 34393220 Reanalysis of inconclusive exome/genome sequencing data increases the diagnosis yield of patients with rare diseases. However, the cost and efforts required for reanalysis prevent its routine implementation in research and clinical environments. The Solve-RD project aims to reveal the molecular causes underlying undiagnosed rare diseases. One of the goals is to implement innovative approaches to reanalyse the exomes and genomes from thousands of well-studied undiagnosed cases. The raw genomic data is submitted to Solve-RD through the RD-Connect Genome-Phenome Analysis Platform (GPAP) together with standardised phenotypic and pedigree data. We have developed a programmatic workflow to reanalyse genome-phenome data. It uses the RD-Connect GPAP's Application Programming Interface (API) and relies on the big-data technologies upon which the system is built. We have applied the workflow to prioritise rare known pathogenic variants from 4411 undiagnosed cases. The queries returned an average of 1.45 variants per case, which first were evaluated in bulk by a panel of disease experts and afterwards specifically by the submitter of each case. A total of 120 index cases (21.2% of prioritised cases, 2.7% of all exome/genome-negative samples) have already been solved, with others being under investigation. The implementation of solutions as the one described here provide the technical framework to enable periodic case-level data re-evaluation in clinical settings, as recommended by the American College of Medical Genetics. The Solve-RD project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 779257. Data were analysed using the RD‐Connect Genome‐Phenome Analysis Platform, which received funding from EU projects RD‐Connect, Solve-RD and EJP-RD (grant numbers FP7 305444, H2020 779257, H2020 825575), Instituto de Salud Carlos III (grant numbers PT13/0001/0044, PT17/0009/0019; Instituto Nacional de Bioinformática, INB) and ELIXIR Implementation Studies. We acknowledge support of the Spanish Ministry of Economy, Industry and Competitiveness (MEIC) to the EMBL partnership, the Centro de Excelencia Severo Ochoa and the CERCA Programme/Generalitat de Catalunya. We also acknowledge the support of the Generalitat de Catalunya through Departament de Salut and Departament d’Empresa i Coneixement and the Co-financing by the Spanish Ministry of Economy, Industry and Competitiveness (MEIC) with funds from the European Regional Development Fund (ERDF) corresponding to the 2014-2020 Smart Growth Operating Program.

Abstract

For the first time in Europe hundreds of rare disease (RD) experts team up to actively share and jointly analyse existing patient's data. Solve-RD is a Horizon 2020-supported EU flagship project bringing together >300 clinicians, scientists, and patient representatives of 51 sites from 15 countries. Solve-RD is built upon a core group of four European Reference Networks (ERNs; ERN-ITHACA, ERN-RND, ERN-Euro NMD, ERN-GENTURIS) which annually see more than 270,000 RD patients with respective pathologies. The main ambition is to solve unsolved rare diseases for which a molecular cause is not yet known. This is achieved through an innovative clinical research environment that introduces novel ways to organise expertise and data. Two major approaches are being pursued (i) massive data re-analysis of >19,000 unsolved rare disease patients and (ii) novel combined -omics approaches. The minimum requirement to be eligible for the analysis activities is an inconclusive exome that can be shared with controlled access. The first preliminary data re-analysis has already diagnosed 255 cases form 8393 exomes/genome datasets. This unprecedented degree of collaboration focused on sharing of data and expertise shall identify many new disease genes and enable diagnosis of many so far undiagnosed patients from all over Europe. The Solve-RD project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 779257. This research is supported (not financially) by four ERNs: (1) The ERN for Intellectual Disability, Telehealth and Congenital Anomalies (ERN-ITHACA)-Project ID No 869189; (2) The ERN on Rare Neurological Diseases (ERN-RND)-Project ID No 739510; (3) The ERN for Neuromuscular Diseases (ERN Euro-NMD)-Project ID No 870177; (4) The ERN on Genetic Tumour Risk Syndromes (ERN GENTURIS)-Project ID No 739547. The ERNs are co-funded by the European Union within the framework of the Third Health Programme. Open Access funding enabled and organized by Projekt DEAL. Sí

Abstract

Orientador: Fernanda Klein Marcondes Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Odontologia de Piracicaba Resumo: O objetivo deste trabalho foi analisar a influência do sexo e do ciclo estral nas respostas metabólicas e hormonais em ratos submetidos a estresse agudo. Ratos com 3 meses de idade, machos e fêmeas ovariectomizadas, ou com ciclo estral regular, foram usados (n = 7-11/grupo). Após a identificação da fase do ciclo estral, manipulação (machos) ou 21 dias após a castração, os animais foram submetidos a uma sessão de natação. Imediatamente após a aplicação do estresse, os animais foram sacrificados sob anestesia para coleta do sangue e dos tecidos. Estes procedimentos também foram realizados em animais controle. Amostras do fígado, coração, músculos sóleo, gastrocnêmio vermelho e branco foram usados para determinação da concentração tecidual de glicogênio (método colorimétrico do fenol-sulfúrico). Após a coleta de sangue e centrifugação, o plasma foi usado para determinação da concentração plasmática de glicose, triglicerídeos, corticosterona, estradiol e progesterona. A glicose e o triglicerídeo plasmáticos foram determinados por ensaios enzimáticos-colorimétricos. As determinações hormonais foram feitas por radioimunoensaio. Os dados foram analisados por ANOVA bifatorial seguida do teste de Tukey com nível de significância 5%. Ratos machos e fêmeas em diestro controle apresentaram maior concentração de glicogênio hepático quando comparados às demais fases do ciclo estral. A natação induziu uma diminuição neste parâmetro em todos os grupos analisados. Com relação ao glicogênio no músculo cardíaco, ratas em metaestro controle apresentaram menor concentração comparadas aos demais grupos e o estresse por natação causou mobilização em todos os grupos, exceto nesta fase do ciclo estral. Ratos machos e ratas em proestro controle apresentaram respectivamente concentração estatisticamente maior e menor de glicogênio no músculo sóleo comparados aos demais grupos e o estresse por natação induziu uma diminuição deste carboidrato em machos e fêmeas em estro, sem ocorrer alteração nas demais fases. Com relação ao glicogênio nos músculos gastrocnêmico vermelho e branco, machos apresentaram maior concentração basal deste polissacarídeo comparado aos demais grupos controle. Neste tecido o estresse por natação induziu diminuição nas concentrações de glicogênio em todos os grupos analisados. O grupo de ratas em metaestro controle apresentou maior glicemia em relação aos demais grupos. Após o estresse, ratos machos e fêmeas em proestro e em diestro apresentaram elevação neste parâmetro, sem alteração em fêmeas em estro e em metaestro. Com relação às concentrações plasmáticas de triglicerídeos, ratas em diestro controle apresentaram valores mais elevados que os demais grupos. Machos, fêmeas em proestro, estro e em metaestro submetidos à natação apresentaram elevação neste parâmetro, enquanto que o grupo de ratas em diestro apresentou diminuição. Ratas em metaestro apresentaram maiores concentrações plasmáticas de corticosterona em relação aos demais grupos controle. Após o estresse, houve elevação neste parâmetro em todos os animais, validando o modelo de estresse utilizado, porém este aumento foi menor em machos. As concentrações basais de estradiol foram mais elevadas em ratas em proestro em relação aos outros grupos analisados. Após a sessão de natação somente nesta fase foi observado aumento, sem alterações nas demais fases do ciclo estral. Com relação à concentração plasmática de progesterona, ratas em metaestro controle apresentaram concentração mais elevada comparadas às demais fases. O estresse induziu aumento e queda respectivamente no metaestro e no proestro. Desta forma, o sexo e o ciclo estral influenciaram a mobilização tecidual de glicogênio, a glicemia, a concentração plasmática de triglicerídeos e a secreção de corticosterona. Também, o ciclo estral influenciou a secreção de estradiol e progesterona após estresse agudo por natação Abstract: The aim of this work was to analyze the influence of the sex and of the estrous cycle in the metabolic and hormonal responses from rats submitted to acute stress. Bilaterally ovariectomized rats with 3 months of age, males and females, with regular estrous cycle, were used (n = 7-11/grupo). After the identification of the phase of the estrous cycle, manipulation (male) or 21 days after the ovariectomizared, the animals were submitted to one swimming session. Immediately after the stress session, the animals were sacrificed under anesthesia for collection of the blood and tissues. These procedures were also done in control animals. Samples of liver, cardiac, soleus, red and white gastrocnemius muscles were used for glycogen determination (phenol-sulphuric method). After the collection of blood and centrifugation, the plasma was used for determination of the concentration of glucose, triacylglicerol, corticosterone, estradiol and progesterone. The plasmatic glucose and triacylglicerol levels were determined by enzymatic-colorimetric assay. The hormonal determinations were made by radioimunoassay. The data were analyzed by bifactorial ANOVA followed of the Tukey test with level of significance 5%. Male and Female rats in diestrus and ovareictomized control presented higher concentration of hepatic glycogen when compared to the other phases of the estrous cycle. Swimming induced a decreased in this parameter in all groups. Metestrus control rats presented lower glycogen concentration compared to the other control groups. Stress caused its mobilization in all the groups, but not in females at metestrus. Control male and female rats at proestrus showed respectively higher and lower concentration of glycogen in the soleus muscle compared to the other groups. Swimming stress decreased these levels only in males and female rat at estrus. Male and females ovarietomized rats presented higher basal concentration of glycogen in the muscles gastrocnemius red and white, compared to the other control groups. In this tissue the stress induced reduction in the glycogen concentrations in all groups. Control female rats at metestrus presented glucose plasmatic higher in relation to other control groups. After the swimming session, males and ovariectomized and at proestrus and diestrus females presented an increase in this parameter, without alteration in females at estrus and metestrus. Control female at diestrus presented higher plasmatic concentrations of triacylglicerol compared to the other control groups. In males, females at proestrus, estrus and metestrus swimming stress increased this parameter, and reduced it at diestrus female rats. Rats at metestrus presented higher plasmatic concentration of corticosterone compared to other control groups. After the stress, there was an increase in this parameter in all groups, validating the model of stress used. However this increase was lower in males. The basal concentration of estradiol was higher in rats at proestrus compared to the other control groups. After swimming stress the levels of this hormone increased in females at proestrus at control proestrus, without changes in the other groups. Rats at metestrus presented higher plasmatic concentration of progesterone compared to the other phases. Stress increased and decreased this hormone levels respectively at metestrus and proestrus. In summary, the sex and the estrous cycle influenced the tissue glycogen mobilization, glucose and triacylglicerol and corticosterone secretion after acute stress. Also, the estrous cycle influenced the estradiol and progesterone production after acute swimming stress Mestrado Fisiologia Oral Mestre em Odontologia

Abstract

Acetylxylan esterases (AXEs) are essential enzymes that break down the acetyl groups in acetylated xylan found in plant cell walls polysaccharides. They work synergistically with backbone-depolymerizing xylanolytic enzymes to accelerate the degradation of complex polysaccharides. In this study, we cloned the gene axeA, which encodes the acetylxylan esterase from Aspergillus nidulans FGSC A4 (AxeAN), into the pEXPYR expression vector and introduced it into the high protein-producing strain A. nidulans A773. The purified AxeAN, with a molecular weight of 33.5 kDa as confirmed by SDS-PAGE, was found to be active on ρ-nitrophenyl acetate (ρNPA), exhibiting a remarkably high specific activity (170 U mg -1 ) at pH 7.0 and 55 °C. AxeAN demonstrated stability over a wide pH range (5.5-9.0), retaining >80% of its initial activity after 24 h. The K M and V max were 0.098 mmol L -1 and 320 U mg -1 , respectively, using ρNPA as a substrate. We also evaluated the synergistic effect of AxeAN with an endo-1,4-β-xylanase from Malbranchea pulchella (MpXyn10) in the hydrolysis of four different xylans (Birchwood, Beechwood, Oat spelt, and Arabinoxylan) to produce xylooligosaccharides (XOS). The best results were obtained using Birchwood xylan as substrate and MpXyn10-AxeAN as biocatalysts after 24 h of reaction (50 °C), with a XOS-yield of 91%, value 41% higher when compared to MpXyn10 (XOS-yield of 63%). These findings showed the potential of the application of AxeAN, together with other xylanases, to produce xylooligosaccharides with high purity and other products with high added value in the field of lignocellulosic biorefinery., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Abstract

Industrial use of Novozym 435 in synthesis of structured lipids and biodiesel via alcoholysis is limited by mass transfer effects of the glycerides through immobilized enzymes and its low operational stability under operation conditions. To better understand this, differently modified Novozym 435 preparations, differing in their surface nature and in their interactions with reactants, have been compared in the alcoholysis of Camelina sativa oil. The three modifications performed have been carried out under conditions where all exposed groups of the enzyme have been modified. These modifications were: 2,4,6-trinitrobenzensulfonic acid (Novo-TNBS), ethylendiamine (Novo-EDA) and polyethylenimine (Novo-PEI). Changes in their operational performance are analyzed in terms of changes detected by scan electron microscopy in the support morphology. The hydrophobic nature of the TNBS accelerates the reaction rate; t-ButOH co-solvent swells the macroporous acrylic particles of Lewatit VP OC 1600 in all biocatalysts, except in the case of Novo-PEI. This co-solvent only increases the maximal conversions obtained at 24h using the modified biocatalysts. t-ButOH reduces enzyme inactivation by alcohol and water. In a co-solvent system, these four biocatalysts remain fully active after 14 consecutive reaction cycles of 24h, but only Novo-TNBS yields maximal conversion before cycle 5. Some deposits on biocatalyst particles could be appreciated during reuses, and TNBS derivatization diminishes the accumulation of product deposits on the catalyst surface. Most particles of commercial Novozym(®) 435 are broken after operation for 14 reaction cycles. The broken particles are fully active, but they cause problems of blockage in filtration operations and column reactors. The three derivatizations studied make the matrix particles more resistant to rupture., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Abstract

Lipase from Thermomyces lanuginosus (TLL) and lipase B from Candida antarctica (CALB) have been immobilized on divinylsulfone (DVS) activated agarose beads at pH 10 for 72 h. Then, as a reaction end point, very different nucleophiles have been used to block the support and the effect of the nature of the blocking reagent has been analyzed on the features of the immobilized preparations. The blocking has generally positive effects on enzyme stability in both thermal and organic solvent inactivations. For example, CALB improved 7.5-fold the thermal stability after blocking with imidazole. The effect on enzyme activity was more variable, strongly depending on the substrate and the experimental conditions. Referring to CALB; using p-nitrophenyl butyrate (p-NPB) and methyl phenylacetate, activity always improved by the blocking step, whatever the blocking reagent, while with methyl mandelate or ethyl hexanoate not always the blocking presented a positive effect. Other example is TLL-DVS biocatalyst blocked with Cys. This was more than 8 times more active than the non-blocked preparation and become the most active versus p-NPB at pH 7, the least active versus methyl phenylacetate at pH 5 but the third one most active at pH 9, versus methyl mandelate presented lower activity than the unblocked preparation at pH 5 and versus ethyl hexanoate was the most active at all pH values. That way, enzyme specificity could be strongly altered by this blocking step., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Abstract

Lecitase Ultra has been immobilized on cyanogen bromide agarose (via covalent attachment) and on octyl agarose (via physical adsorption on the hydrophobic support by interfacial activation). Both immobilized preparations have been incubated in dextran sulfate (DS) or polyethylenimine (PEI) solutions to coat the enzyme surface. Then, the activity versus different substrates and under different experimental conditions was evaluated. The PEI coating generally produced a significant increase in enzyme activity, in some cases even by more than a 30-fold factor (using the octyl-Lecitase at pH 5 in the hydrolysis of methyl phenyl acetate). In opposition, the DS coating usually produced some negative effects on the enzyme activity. The rate of irreversible inhibition of the covalent preparation using diethyl p-nitrophenylphosphate did not increase after PEI coating suggesting that the increase in Lecitase activity is not a consequence of the stabilization of the open form of Lecitase. Moreover, the coating greatly increased the stability of the immobilized Lecitase, for example using DS and the covalent preparation, the half-life was increased by a 30-fold factor in 30% acetonitrile. The stabilizing effect was not found in all cases, in certain cases even a certain destabilization is found (e.g., octyl-Lecitase-DS at pH 7). Thus, the effects of the ionic polymer coating strongly depend on the substrate, experimental conditions and immobilization technique employed., (Copyright © 2014 Elsevier Inc. All rights reserved.)
