13. Epitope‐directed anti‐SARS‐CoV‐2 scFv engineered against the key spike protein region could block membrane fusion.

Abstract

The newly emerged SARS‐CoV‐2 causing coronavirus disease (COVID‐19) resulted in >500 million infections. A great deal about the molecular processes of virus infection in the host is getting uncovered. Two sequential proteolytic cleavages of viral spike protein by host proteases are prerequisites for the entry of the virus into the host cell. The first cleavage occurs at S1/S2 site by the furin protease, and the second cleavage at a fusion activation site, the S2′ site, by the TMPRSS2 protease. S2′ cleavage site is present in the S2 domain of spike protein followed by a fusion peptide. Given the S2′ site to be conserved among all the SARS‐CoV‐2 variants, we chose an S2′ epitope encompassing the S2′ cleavage site and generated single‐chain antibodies (scFvs) through an exhaustive phage display library screening. Crystal structure of a scFv in complex with S2′ epitope was determined. Incidentally, S2′ epitope in the scFv bound structure adopts an alpha‐helical conformation equivalent to the conformation of the epitope in the spike protein. Furthermore, these scFvs can bind to the spike protein expressed either in vitro or on the mammalian cell surface. We illustrate a molecular model based on structural and biochemical insights into the antibody‐S2′ epitope interaction emphasizing scFvs mediated blocking of virus entry into the host cell by restricting the access of TMPRSS2 protease and consequently inhibiting the S2′ cleavage competitively.

Abstract

The establishment and maintenance of pregnancy in humans proceed through a continuous change of biochemical and biophysical processes. It requires a constant interaction between the fetus and the maternal system. The present prospective study aims to elucidate changes in salivary proteome from the early to middle stages of term pregnancy, and establishing an expressional trajectory for modulated proteins. To date, a comprehensive characterization of the longitudinal salivary proteome in pregnancy has not been performed and it is our immediate interest. In the discovery phase, maternal saliva (N = 20) at 6–13, 18–21, and 26–29 weeks of gestation was analyzed using level-free proteomics (SWATH-MS) approach. The expression levels of 65 proteins were found to change significantly with gestational age and distributed into two distinct clusters with a unique expression trajectory. The results revealed that altered proteins are involved in maternal immune modulation, metabolism, and host defense mechanism. Further, verification of 12 proteins was employed using targeted mass spectrometry (MRM-MS) in a separate subset of saliva (N = 14). The MRM results of 12 selected proteins confirmed a similar expression pattern as in SWATH-MS analysis. Overall, the results not only demonstrate the longitudinal maternal saliva proteome for the first time but also set the groundwork for comparative analysis between term birth and adverse pregnancy outcomes.

Abstract

Summary: The non‐specific lipid transfer proteins (nsLTPs) are multifunctional seed proteins engaged in several different physiological processes. The nsLTPs are stabilized by four disulfide bonds and exhibit a characteristic hydrophobic cavity, which is the primary lipid binding site. While these proteins are known to transfer lipids between membranes, the mechanism of lipid transfer has remained elusive. Four crystal structures of nsLTP from Solanum melongena, one in the apo‐state and three myristic acid bound states were determined. Among the three lipid bound states, two lipid molecules were bound on the nsLTP surface at different positions and one was inside the cavity. The lipid‐dependent conformational changes leading to opening of the cavity were revealed based on structural and spectroscopic data. The surface‐bound lipid represented a transient intermediate state and the lipid ultimately moved inside the cavity through the cavity gate as revealed by molecular dynamics simulations. Two critical residues in the loop regions played possible 'gating' role in the opening and closing of the cavity. Antifungal activity and membrane permeabilization effect of nsLTP against Fusarium oxysporum suggested that it could possibly involve in bleaching out the lipids. Collectively, these studies support a model of lipid transfer mechanism by nsLTP via intermediate states. Significance Statement: A model of lipid transfer mechanism of nsLTP from Solanum melongena has been proposed through intermediate crystal structures with lipid bound at different sites.

Abstract

The structure of the MP‐4 protein was previously determined at a resolution of 2.8 Å. Owing to the unavailability of gene‐sequence information at the time, the side‐chain assignment was carried out on the basis of a partial sequence available through Edman degradation, sequence homology to orthologs and electron density. The structure of MP‐4 has now been determined at a higher resolution (2.22 Å) in another space group and all of the structural inferences that were presented in the previous report of the structure were validated. In addition, the present data allowed an improved assignment of side chains and enabled further analysis of the MP‐4 structure, and the accuracy of the assignment was confirmed by the recently available gene sequence. The study reinforces the traditional concept that conservative interpretations of relatively low‐resolution structures remain correct even with the availability of high‐resolution data.

Abstract

Globally, preterm birth is a major public health problem. In India, 3.6 million of the 27 million infants born annually are preterm. Risk stratification of women based on multidimensional risk factors assessed during pregnancy is critical for prevention of preterm birth. A cohort study of pregnant women was initiated in May 2015 at the civil hospital in Gurugram, Haryana, India. Women are enrolled within 20 weeks of gestation and are followed until delivery and once postpartum. The objectives are to identify clinical, epidemiologic, genomic, epigenomic, proteomic, and microbial correlates; discover molecular-risk markers by using an integrative -omics approach; and generate a risk-prediction algorithm for preterm birth. We describe here the longitudinal study design, methodology of data collection, and the repositories of data, biospecimens, and ultrasound images being created. A total of 4,326 pregnant women, with documented evidence of recruitment before 20 weeks of gestation, have been enrolled through March 2018. We report baseline characteristics and outcomes of the first 2,000 enrolled participants. A high frequency of preterm births (14.9% among 1,662 live births) is noteworthy. The cohort database and the repositories will become global resources to answer critical questions on preterm birth and other birth outcomes. [ABSTRACT FROM AUTHOR]

Abstract

The immune system is capable of making antibodies against anything that is foreign, yet it does not react against components of self. In that sense, a fundamental requirement of the body's immune defense is specificity. Remarkably, this ability to specifically attack foreign antigens is directed even against antigens that have not been encountered a priori by the immune system. The specificity of an antibody for the foreign antigen evolves through an iterative process of somatic mutations followed by selection. There is, however, accumulating evidence that the antibodies are often functionally promiscuous or multi-specific which can lead to their binding to more than one antigen. An important cause of antibody cross-reactivity is molecular mimicry. Molecular mimicry has been implicated in the generation of autoimmune response. When foreign antigen shares similarity with the component of self, the antibodies generated could result in an autoimmune response. The focus of this review is to capture the contrast between specificity and promiscuity and the structural mechanisms employed by the antibodies to accomplish promiscuity, at the molecular level. The conundrum between the specificity of the immune system for foreign antigens on the one hand and the multi-reactivity of the antibody on the other has been addressed. Antibody specificity in the context of the rapid evolution of the antigenic determinants and molecular mimicry displayed by antigens are also discussed. [ABSTRACT FROM AUTHOR]

Abstract

Proteins belonging to cupin superfamily are known to have critical and diverse physiological functions. However, 7S globulins family, which is also a part of cupin superfamily, were undermined as only seed storage proteins. Structure determination of native protein -- Vic_CAPAN from Capsicum annuum -- was carried out, and its physiological functions were explored after purifying the protein by ammonium sulfate precipitation followed by size exclusion chromatography. The crystal structure of vicilin determined at 2.16 Å resolution revealed two monomers per asymmetric unit which are juxtaposed orthogonal with each other. Vic_CAPAN consists predominately of β-sheets that folds to form a β-barrel structure commonly called cupin fold. Each monomer of Vic_CAPAN consists of two cupin fold domains, N-terminal and C-terminal, which accommodate two different ligands. A bound ligand was identified at the C-terminal cupin fold in the site presumably conserved for metabolites in the crystal structure. The ligand was confirmed to be salicylic acid through mass spectrometric analysis. A copper-binding site was further observed near the conserved ligand-binding pocket, suggesting possible superoxide dismutase activity of Vic_CAPAN which was subsequently confirmed biochemically. Vicilins from other sources did not exhibit this activity indicating functional specificity of Vic_CAPAN. Discovery of bound salicylic acid, which is a known regulator of antioxidant pathway, and revelation of superoxide dismutase activity suggest that Vic_CAPAN has an important role during oxidative stress. As salicylic acid changes the redox state of cell, it may act as a downstream signal for various pathways involved in plant biotic and abiotic stress rescue. [ABSTRACT FROM AUTHOR]

38. Structural and functional studies of differentially O-glycosylated analogs of a thrombin inhibitory peptide - variegin.

Author

Abstract

Variegin is a 32-amino acid long thrombin inhibitory peptide isolated from the salivary gland extract of tropical bont tick Amblyomma variegatum. It was identified to be O-glycosylated on its Thr-14 side chain, and this glycosylated form was 14-fold more potent than that of its non-glycosylated form. However, as the identity of this glycosylation remained elusive, the mechanistic details underlying its functional impact are not yet known. In this report, we synthesized four different O-glycosylated analogs of variegin bearing physiologically relevant sugars on its Thr-14. Functional characterization of these analogs by enzyme inhibitory kinetics and surface plasmon resonance methods showed that all the synthesized glycopeptides are strong thrombin inhibitors. Structural studies by macromolecular docking identified that the sugar moiety of these peptides can potentially mediate favorable interactions with amino acids at the base of thrombin's autolysis loop. This report, for the first time, describes the impact of differential glycosylation on the function of a thrombin inhibitory peptide and tries to provide structural insights into the relevance of peptide glycosylation in thrombin inhibition.

39. Crystal structure of nonspecific lipid transfer protein from Solanum melongena.

Author

Abstract

Lipids are considered to protect protein allergens from proteolysis and are generally seen to exist in a bound form. One of the well-known plant protein families with bound lipids is non-specific lipid transfer proteins (nsLTPs). Structure-function relationships in the case of the members of non-specific lipid transfer protein family are not clearly understood. As part of exploring the seed proteome, we have analyzed the proteome of a member of Solanaceae family, Solanum melongena (eggplant) and a non-specific lipid transfer protein from S. melongena, SM80.2 was purified, crystallized and the structure was determined at 1.87 Å resolution. Overall, the tertiary structure is a cluster of α-helices forming an internal hydrophobic cavity. Absence of conserved Tyr79, known to govern the plasticity of hydrophobic cavity, and formation of hydrogen bond between Asn79 and Asn36 further reduced the pocket size. Structural analysis of SM80.2 thus gives insight about a new hydrogen bond mediated mechanism followed in closure of the binding pocket. Extra electron densities observed at two different places on the protein surface and not in the cavity could provide interesting physiological relevance. In light of allergenic properties, probably overlapping of epitopic region and ligand binding on surface could be a main reason. This work shows first crystal structure of A-like nsLTP with a close binding pocket and extra density on the surface suggesting a plausible intermediate state during transfer. [ABSTRACT FROM AUTHOR]

Abstract

Structure determination using X-ray crystallography involves collection of diffraction data, determination of initial phases followed by iterative rounds of model building and crystallographic refinement to improve the phases and minimize the differences between calculated and observed structure factors. At each of these stages, a variety of statistical filters exist to ensure appropriate validation. Biologically important observations often come from interpretations of signals that need to be carefully deciphered from noise, and therefore human intervention is as important as the automated methods and filters. Currently, all structural data are deposited in the Protein Data Bank (PDB), and this repository is continuously evolving to incorporate new developments in macromolecular crystallography. The journals that publish data arising from structural studies modulate their policies to take cognizance of new improved methodologies. Together, the PDB and journals have evolved an accepted protocol to ensure the integrity of crystallographic results. As a result, the quality of available data and associated interpretations have improved over the years. Typically, if there are differences regarding the mechanism of action of a protein revealed by crystallography then new experiments are carried out to provide further evidence for or against a particular hypothesis. Hence, the scientific systems in structural biology are robust and to a large extent capable of correcting any errors in interpretation of structural results. However, this process is hindered by spurious challenges to published research, based on misuse of validation mechanisms. Such activities are counterproductive and will cause damage to the field of structural biology. © 2017 IUBMB Life, 69(8):563-571, 2017 [ABSTRACT FROM AUTHOR]

42. Multiple target sites for designing candidate drugs.

Author

Salunke, Dinakar M.

Abstract

Rational drug discovery strategy requires a design of small molecules as candidate drugs which can specifically inhibit a target protein or any other macromolecule and effectively interfere in a defined physiological process. One of the important bacterial protein targets aimed toward developing new antibiotics is peptidyl-tRNA hydrolase (Pth). The discovery that cytarabine, a known anticancer drug, binds to Pth from Acinetobacter baumannii in a cleft located away from the catalytic site of this enzyme, published in Biochemical Journal, opens up interesting new avenues for drug design. An approach involving crystallographic identification of multiple ligand-binding sites on a target protein surface could enable iterative optimization of multiple high-affinity ligands, which may synergistically interfere in the target function with enhanced effect.

Abstract

Affinity maturation is associated with reduced malleability of the paratope that optimizes an antibody to bind to the bonafide antigen with high specificity and affinity. However, it has been illustrated that mature antibodies tend to exhibit promiscuity despite acquisition of a relatively rigid binding pocket. Such an attribute is contrary to the established paradigm of specificity in antigen recognition. In this review, an explicit dissection of the underlying mechanisms fostering such versatility in mature antibodies has been done. Polyspecificity is essentially achieved by undergoing minimal structural rearrangement at the paratope complemented with plasticity in interaction with antigen. Besides, the structural invariance of the antigen across species could modulate mature antibody specificity. Polyreactivity has been well documented for germline antibodies as broad spectrum antibody repertoire amplification is primarily governed by recombination event of the genetic machinery, which is further expanded at the structural and functional level of interaction. Degenerate specificity in antigen recognition obviates the need to produce distinct antibody for every incoming epitope © 2015 IUBMB Life, 67(7):498-505, 2015 [ABSTRACT FROM AUTHOR]

Ag recognition by independent primary Abs against a small flexible Ag with overlapping epitopes was analyzed to address the determinants of Ag specificity during the initial encounter. Crystal structures of two distinct dodecapeptide Ags, GDPRPSYISHLL and PPYPAWHAPGNI, in complex with the germline mAb 36-65 were determined and compared with the structures of the same Ags bound to another independent germline mAb, BBE6.12H3. For each peptide Ag, the two germline mAbs recognized overlapping epitopes, but in different topologies. The peptide structures differed, and the two paratopes attained discrete conformations, leading to different surface topologies, in a mode that can be described as adjustable locks and flexible keys. This is in contrast to mature mAbs, in which conformational convergence of different paratopes while binding to a common epitope in a similar conformation has been reported. These results suggest that the primary immune receptor repertoire is highly versatile as compared with its mature counterpart. Germline and mature mAbs adopt distinct mechanisms for recognizing a flexible epitope. Whereas conservation of conformational repertoire is a key characteristic of mature mAbs achieved through affinity maturation, the germline mAbs, at the initial stages of Ag encounter, maintain substantial plasticity, accommodating a broad specificity repertoire.

Abstract

Immune complexes involving diverse antigens and corresponding antibodies were analyzed for mapping conformational transitions of an antibody before antigen binding, upon antigen binding and after antigen release. Molecular dynamics simulations of the two comprehensive datasets consisting of the antigen-free and antigen-bound structures of the germline antibodies 36-65 and BBE6.12H3 provided mechanistic model of antigen encounter by primary antibodies. While native germline antibodies exhibit substantial mobility in the antigen-combining sites, their antigen-bound states exhibit relatively rigid conformations, even in the absence of the antigen suggesting preservation of the structural state after antigen release. It is proposed that acquired rigidity by a germline antibody upon antigen binding may be the first step in affinity maturation in favor of that antigen. [ABSTRACT FROM AUTHOR]

Abstract

Background: Transthyretin (TTR) is a homotetrameric serum and cerebrospinal fluid protein that transports thyroxine (T4) and retinol by binding to retinol binding protein. Rate-limiting tetramer dissociation and rapid monomer misfolding and disassembly of TTR lead to amyloid fibril formation in different tissues causing various amyloid diseases. Based on the current understanding of the pathogenesis of TTR amyloidosis, it is considered that the inhibition of amyloid fibril formation by stabilization of TTR in native tetrameric form is a viable approach for the treatment of TTR amyloidosis. Methodology and Principal Findings: We have examined interactions of the wtTTR with a series of compounds containing various substitutions at biphenyl ether skeleton and a novel compound, previously evaluated for binding and inhibiting tetramer dissociation, by x-ray crystallographic approach. High resolution crystal structures of five ligands in complex with wtTTR provided snapshots of negatively cooperative binding of ligands in two T4 binding sites besides characterizing their binding orientations, conformations, and interactions with binding site residues. In all complexes, the ligand has better fit and more potent interactions in first T4 site i.e. (AC site) than the second T4 site (BD site). Together, these results suggest that AC site is a preferred ligand binding site and retention of ordered water molecules between the dimer interfaces further stabilizes the tetramer by bridging a hydrogen bond interaction between Ser117 and its symmetric copy. Conclusion: Novel biphenyl ether based compounds exhibit negative-cooperativity while binding to two T4 sites which suggests that binding of only single ligand molecule is sufficient to inhibit the TTR tetramer dissociation.

Abstract

The mechanistic basis for efficient combating of the infinite range of foreign Ags by the limited repertoire of naive Abs expressed on primary B cell surfaces during their first encounter was addressed through elegantly designed crystallographic analyses. Resolution of the discrepancy arising from the limited number of possible germline Ab receptors on primary B cells for recognizing the unlimited pool of possible Ags has been attempted by invoking the degenerate recognition potential of the germline Abs. Structural analyses of germline mAb BBE6.12H3 in an Ag-free state, as well as bound to four different peptide Ags, established the correlation of its degenerate specificity with conformational versatility of the paratope. Six distinct paratope topologies observed for a single germline mAb provided a quantitative description of the primary Ag recognition repertoire at the tertiary structural level. Each of the four different peptide Ags was bound specifically to a distinct conformation of the paratope, which was also different from that of the Ag-free states of the same germline mAb. A minimal conserved motif in the pristine Ag-combining site essential for multispecificity and Ag binding-mediated change in the elbow angle of Fab was also discernible. It is proposed that the generation of a primary Ab repertoire involves large, yet finite, germline Ab clones, each capable of adopting discrete conformations, which in turn exhibit diverse binding modes.

49. The structure of a haemopexin-fold protein from cow pea ( Vigna unguiculata) suggests functional diversity of haemopexins in plants.

Abstract

The haemopexin fold is present in almost all life forms and is utilized for carrying out diverse physiological functions. The structure of CP4, a haemopexin-fold protein from cow pea ( Vigna unguiculata), was determined at 2.1 Å resolution. The protein exists as a monomer both in solution and in the crystal. The structure revealed a typical four-bladed β-propeller topology. The protein exhibits 42% sequence similarity to LS-24 from Lathyrus sativus, with substantial differences in the surface-charge distribution and in the oligomeric state. A structure-based sequence analysis of haemopexin-fold proteins of plant and mammalian origin established a sequence signature associated with the haemopexin motif. This signature sequence enabled the identification of other proteins with possible haemopexin-like topology of both plant and animal origin. Although CP4 shares a structural fold with LS-24 and other haemopexins, biochemical studies indicated possible functional differences between CP4 and LS-24. While both of these proteins exhibit spermine-binding potential, CP4 does not bind to haem, unlike LS-24. [ABSTRACT FROM AUTHOR]

Abstract

Mycobacterium tuberculosis (Mtb), a dreaded pathogen, has a unique cell envelope composed of high fatty acid content that plays a crucial role in its pathogenesis. Acetyl Coenzyme A Carboxylase (ACC), an important enzyme that catalyzes the first reaction of fatty acid biosynthesis, is biotinylated by biotin acetyl-CoA carboxylase ligase (BirA). The ligand-binding loops in all known apo BirAs to date are disordered and attain an ordered structure only after undergoing a conformational change upon ligand-binding. Here, we report that dehydration of Mtb-BirA crystals traps both the apo and active conformations in its asymmetric unit, and for the first time provides structural evidence of such transformation. Recombinant Mtb-BirA was crystallized at room temperature, and diffraction data was collected at 295 K as well as at 120 K. Transfer of crystals to paraffin and paratone-N oil (cryoprotectants) prior to flash-freezing induced lattice shrinkage and enhancement in the resolution of the X-ray diffraction data. Intriguingly, the crystal lattice rearrangement due to shrinkage in the dehydrated Mtb-BirA crystals ensued structural order of otherwise flexible ligand-binding loops L4 and L8 in apo BirA. In addition, crystal dehydration resulted in a shift of ∼3.5 Å in the flexible loop L6, a proline-rich loop unique to Mtb complex as well as around the L11 region. The shift in loop L11 in the C-terminal domain on dehydration emulates the action responsible for the complex formation with its protein ligand biotin carboxyl carrier protein (BCCP) domain of ACCA3. This is contrary to the involvement of loop L14 observed in Pyrococcus horikoshii BirA-BCCP complex. Another interesting feature that emerges from this dehydrated structure is that the two subunits A and B, though related by a noncrystallographic twofold symmetry, assemble into an asymmetric dimer representing the ligand-bound and ligand-free states of the protein, respectively. In-depth analyses of the sequence and the structure also provide answers to the reported lower affinities of Mtb-BirA toward ATP and biotin substrates. This dehydrated crystal structure not only provides key leads to the understanding of the structure/function relationships in the protein in the absence of any ligand-bound structure, but also demonstrates the merit of dehydration of crystals as an inimitable technique to have a glance at proteins in action.
