The enzymology of milk and other products is of enormous significance for the production and quality of almost every dairy product. Milk itself is a complex biological fluid that contains a wide range of enzymes with diverse activities, some of which have identifiable functions while others are present as an accidental consequence of the mechanism of milk secretion. Over time milk enzymology has become an incredibly essential component of milk and other dairy product production, and with advancing technology and processing techniques, its importance is at its peak. Dairy Enzymology presents an expansive overview of the enzymology of milk and other dairy products, focusing on the use of indigenous and endogenous enzymes in milk and exogenous enzymes in cheese processing. A full section is dedicated to the enzymology of bovine milk, focusing on the main families of indigenous enzymes as well as their potential significance in the mammary gland plus the technological significance for the properties of dairy products. Implications for the manufacture and ripening of cheese plus the use of enzymes such as alkaline phosphatase for measuring heat treatment in milk are explored in full, and the role of milk protease plasmin and other indigenous enzymes in the age-gelation is focused on. Further sections focus on enzymes found in raw milk and enzymes deliberately added for manufacture or modification of properties and the manufacture of food ingredients from dairy-derived ingredients. The key bacterial families are discussed in depth as well as their known contributions to the quality of dairy products. With its comprehensive scope and fully up-to-date coverage of dairy product enzymology, this text is a singular source for researchers looking to understand this essential dairy processing aspect.

This book provides a comprehensive overview of the recent developments achieved in the field of chemo/enzymatic cascades with topics spanning from design (in vitro and in vivo) to kinetic- and process modelling as well as process control. Opportunities and challenges of building multi-step chemo/enzymatic reactions are discussed, whereby the latter are critically assessed in each chapter and methods to ease the implementation are explored. Both, multi-enzymatic cascades and chemo-enzymatic cascades are presented with the motivation of combining the strengths of these two worlds (e.g. selectivity, activity and robustness) not neglecting the obstacles and challenges of such endeavour. Furthermore, the use of non-conventional media for catalytic cascade reactions, recent achievements and potential for future developments in a technical environment are addressed.

This book explores the broad and diverse biological and physiological impacts of established and newly discovered cyclic di-nucleotide second messenger signaling systems, while also providing descriptions of the intriguing biochemical characteristics of multiple turnover enzymes and receptors. The respective chapters discuss the commonalities and diversity of cyclic di-GMP, cyclic di-AMP and recently discovered cyclic GMP-AMP signaling systems in manifold Gram-negative and Gram-positive bacteria. The global human pathogens Mycobacterium tuberculosis, Vibrio cholerae, Salmonella typhimurium, Escherichia coli and Streptococcus pneumoniae, the facultative human pathogen Pseudomonas aeruginosa, global plant pathogens as exemplified by Xanthomonas campestris and Burkholderia spp., and the omnipresent probiotic Lactobacilli, as well as environmentally importantphotoautotrophic cyanobacteria, the multicellular Myxococcus xanthus, and chemolithotrophic Acidithiobacillus are among the representatives of the microbial kingdom that are described.In turn, the various aspects of bacterial physiology affected by these signaling systems– e.g. biofilm formation and dispersal, the cell cycle, motility, virulence, production of antimicrobials, fundamental metabolism and osmohomeostasis – are discussed in detail in the context of different microorganisms. Dedicated chapters focus on the population diversity of cyclic dinucleotide signaling systems, their tendency to be horizontally transferred, the cyclic di-GMP signaling system in the social amoeba Dictyostelium, honorary cyclic (di)nucleotides, and the development of strategies for interfering with cyclic dinucleotide signaling in order to manipulate microbial behavior.Taken together, the chapters provide an authoritative source of information fora broad readership: beginners and advanced researchers from various disciplines; individuals seeking a broad overview of cyclic di-nucleotide signaling; and those who want to learn more about specific aspects. Also featuring reviews with a forward-looking perspective, the book offers a valuable source of inspiration for future research directions.

Miles de reacciones químicas tienen lugar en nuestro organismo en cada instante. La mayoría de ellas depende de unas proteínas que actúan como catalizadores, acelerando millones de veces los procesos que ocurren en los seres vivos; sin ellas la vida no sería posible. Estas moléculas son las enzimas, que al operar en condiciones experimentales suaves, se han convertido en pilares esenciales para la sostenibilidad de muchos procesos industriales. El ser humano ha aprovechado el enorme potencial de estos catalizadores biológicos y los produce a gran escala a partir de cultivos de microorganismos para incorporarlos a muchas de nuestras actividades cotidianas: para obtener alimentos saludables (productos sin lactosa, grasa de cacao, zumos, etc.), biocombustibles y polímeros, producir detergentes, tratar prendas textiles, en la producción de antibióticos o incluso en el tratamiento de enfermedades genéticas y en análisis clínicos.

In this book the authors describe how they reproduced the redox functions of biocatalysts artificially. It includes the introduction and discussion of synthetic reactions via electron transfer, hybrid π-conjugated systems, and biorganometallic conjugates as novel redox systems. The work was conducted in pioneering fields based on redox systems, in synthetic organic chemistry, synthetic materials chemistry, and bioorganometallic chemistry. The step-by-step process is illustrated by the three major parts of the book: redox reactions (selective synthetic methods using metal-induced redox reactions), redox systems (design and redox function of conjugated complexes with polyanilines or quinonediimines and molecular bowl sumanene), and design of bioorganometallic conjugates to induce chirality-organized structures (bio-related structurally controlled systems). This systematic and up-to-date description will be of special interest to graduate students who are meeting the new challenges of chemistry, as well as to post-doctoral researchers and other practicing chemists in both academic and industrial settings.

Tryptophan metabolism via kynurenine pathway plays a critical role in both health and a variety of human diseases. This book highlights the known associations between kynurenine pathway and various disease states, as well as examines the current status of drug development and clinical trials of compounds known to alter tryptophan metabolism. The research plays a critical role in molecular targeted therapies directed at altering the kynurenine pathway of tryptophan metabolism. The initial and rate-limiting step of tryptophan metabolism is mediated by one of two enzymes, tryptophan-2,3-dioxygenase (TDO; predominantly in the liver, but also in the brain) and indoleamine-2,3-dioxygenase (IDO; in a host of tissues in response to immune activation). Targeting the enzymes IDO and TDO, as well as other downstream effectors would therefore be likely to generate novel treatment options that would be helpful in a wide variety of clinical settings. This book provides a unique bridge between basic mechanistic understanding of the role of the kynurenine pathway with translational applications and clinical relevance. It will explore the indications that tryptophan metabolism is a potential biomarker of disease activity, can contribute to local and possibly systemic immune suppression in cancer, and is an attractive target for which a variety of inhibitors are readily available.

This book presents basic and extensive information on the physiological and pathological significance of the protein-modifying enzymes, transglutaminases, which are involved in multiple biological events by catalyzing a unique and important posttranslational modification reaction, cross-linking of proteins, and interacting with a large number of proteins inside and outside of cells. Although several of their essential physiological roles have been revealed, many unknown and so far not fully understood functions have remained. In humans, there are eight active isozymes having distinct tissue and subcellular distribution patterns with different substrates and physiological roles. Accordingly, aberrant regulation of the enzyme reactions or expression may lead to or has been implicated in various pathologies including neurodegeneration, fibrosis, cancer, inflammation, celiac disease, and hemostasis disorders.To provide those who are new to the field with basic knowledge and recent information on transglutaminase structures and reactions, the mechanism by which transglutaminases modify substrate proteins and their contributions to multiple biological phenomena as well as disease phenotypes, the publication of the present transglutaminase book was planned, to consist of review articles by 17 expert investigators working in this exciting area of research. The book contains detailed information related to several transglutaminases from aspects in chemical and cellular biology, medical sciences, and biotechnology that will also supply starting points for drug discovery. Although many prominent findings have been published in recent years, this type of comprehensive review book has been missing in the scientific literature. This volume will be useful for investigators who either currently work on or will start addressing transglutaminase-related research, and beyond that, for a broad audience in the scientific community.

Enzyme Technology is one the most promising disciplines in modern biotechnology. In this book, the applications of a wide variety of enzymes are highlighted. Current studies in enzyme technology are focused towards the discovery of novel enzymes (termed “bio-discovery” or “bio-prospecting”) and the identification and elucidation of novel pathways of these novel enzymes with emphasis on their industrial relevance. With the development of molecular techniques and other bioinformatics tools, the time to integrate this subject with other fields in the life sciences has arrived. A rapid expansion of the knowledge base in the field of enzyme biotechnology has occurred over the past few years. Much of this expansion has been driven by the bio-discovery of many new enzymes from a wide range of environments, some extreme in nature, followed by subsequent protein (enzyme) engineering. These enzymes have found a wide range of applications, ranging from bioremediation, bio-monitoring, biosensor development, bioconversion to biofuels and other biotechnologically important value-added products. Hydrolases constitute a major component of the global annual revenue generated by industrial enzymes and the emphasis has therefore been placed on these enzymes and their applications. With the immense interest of researchers active in this area, this book will serve to provide information on current aspects in this field of study. In the current edition, the contributions of many diversified topics towards establishing new directions of research in the area of enzyme biotechnology are described. This book serves to provide a unique source of information to undergraduates, post graduates and doctoral courses in microbiology and biotechnology along with allied life sciences. The present edition of the book covers all important areas of enzyme biotechnology i.e. the wide variety of enzymes in the field of enzyme biotechnology and their industrial applications, new methods andstate-of-the-art information on modern methods of enzyme discovery. This book will act as good resource on most of the current facets of enzyme technology for all students engaged in bioengineering and biotechnology.

Springer Advanced Texts In Chemistry New textbooks at all levels of chemistry appear with great regularity. Some fields like basic biochemistry, organic reaction mechanisms, and chemical thermody­ namics are well represented by many excellent texts, and new or revised editions are published sufficiently often to keep up with progress in research. However, some areas of chemistry, especially many of those taught at the graduate level, suffer from a real lack of up-to-date textbooks. The most serious needs occur in fields that are rapidly changing. Textbooks in these subjects usually have to be written by scientists actually involved in the research that is advancing the field. It is not often easy to persuade such individuals to set time aside to help spread the knowledge they have accumulated. Our goal, in this series, is to pinpoint areas of chemistry where recent progress has outpaced what is covered in any available textbooks, and then seek out and persuade experts in these fields to produce relatively concise but instructive introductions to their fields. These should serve the needs of one semester or one quarter graduate courses in chemistry and biochemistry. In some cases the availability of texts in active research areas should help stimulate the creation of new courses.
