Handbook of Proteolytic Enzymes, Second Edition, Volume 1: Aspartic and Metallo Peptidases is a compilation of numerous progressive research studies on proteolytic enzymes. This edition is organized into two main sections encompassing 328 chapters. This handbook is organized around a system for the classification of peptidases, which is a hierarchical one built on the concepts of catalytic type, clan, family and peptidase. The concept of catalytic type of a peptidase depends upon the chemical nature of the groups responsible for catalysis. The recognized catalytic types are aspartic, cysteine, metallo, serine, threonine, and the unclassified enzymes, while clans and families are groups of homologous peptidases. Homology at the level of a family of peptidases is shown by statistically significant relationship in amino acid sequence to a representative member called the type example, or to another member of the family that has already been shown to be related to the type example. Each chapter discusses the history, activity, specificity, structural chemistry, preparation, and biological aspects of the enzyme. This book will prove useful to enzyme chemists and researchers.

Structure–Function Relationships of Proteolytic Enzymes provides information pertinent to the fundamental aspects of proteolytic enzymes. This book presents the historical role of proteolytic enzyme as a group in protein and enzyme chemistry. Organized into 23 chapters, this book begins with an overview of the results obtained from investigation on the chymotrypsinogens of porcine origin. This text then examines the differences of amino acid sequence between chymotrypsin, trypsin, and elastase that affect the substrate binding site, which reflect the specificity differences between these enzymes. Other chapters consider the kinetic parameters related to the trypsin-catalyzed hydrolysis of several model peptides. This book discusses as well the acetylation of trypsin, which result in functional consequences varying from complete inactivation to promotion of activity. The final chapter deals with the physical properties of stem bromelain in comparison with the data for three other sulfhydryl proteases of plant origin. This book is a valuable resource for enzymologists, microbiologists, and biochemists.

Methods of Soil Enzymology provides the first comprehensive set of vetted methods for studying enzymes in soils. Readers will especially benefit from the step-by-step explanation of the lab procedures, as well as background information for using these methods effectively and analyzing data. Main topics include activity assays, enzyme extraction, and synthetic enzyme complexes. Each method covered includes background informaton, step-by-step descriptions of the procedure, and special comments regarding nuances, pitfalls, and interpretation of the method. Learn the latest research methods, including enzyme extraction methods and procedures for creating synthetic enzyme complexes, as well as the newest ways to use small-scale and high-throughput methods for enzyme activity assays. Written for the researcher, but welcoming to those new to soil enzymology, the introduction includes conceptual information to orient those who are not familiar with these methods but want to use them. In the tradition of SSSA methods books, Methods of Soil Enzymology features a comprehensive approach with a focus on ease of use.

The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms.

Like the popular first edition, this new edition of Proteolytic Enzymes emphasizes practical aspects of the handling, characterization, inhibition, and use of proteolytic enzymes giving general advice and specific examples. The text and protocols have been thoroughly updated to take account of the advances made in the last 10 years in both the increased understanding of the role of peptidases in many critical cellular processes e.g. apoptosis and new technological developments e.g. in recombinant protein expression, protein sequencing, and structural studies. The topics covered are: nomenclature and classification; purification; assay methods; determination of mechanism; inhibition and prevention of unwanted proteolytic activity; characterizing natural inhibitors; proteolytic enzymes in peptide mapping and primary structure elucidation by mass spectrometry and Edman sequencing; limited proteolysis as a structural probe; synthetic function. This book will be as invaluable as the first edition in providing ideas and protocols for scientists either studying proteases or using proteases as a research tool.

In recent years, powered by evolving technologies and experimental design, studies have better illuminated the regulating role of proteolytic enzymes across human development and pathologies. Proteolytic Signaling in Health and Disease provides an in-depth discussion of fundamental physiological and developmental processes regulated by proteases, from protein turnover and autophagy to antigen processing and presentation and major histocompatibility complex (MHC) molecules. Moving on from basic biology, international chapter authors examine a range of pathological conditions associated with proteolysis, including inflammation, wound healing, and cancer. Later chapters discuss the newly discovered network of connected events among proteases (and their inhibitors), the so-called ‘protease web’, and how best to study it. This book also empowers new research with up-to-date analytical methods and step-by-step protocols for studying proteolytic signaling events. Examines biological events triggered by proteolytic enzyme activity across human development and pathologies Discusses the role of proteolytic signaling in inflammation, wound healing, and cancer, among other disease types Features methods and protocols supporting further study of proteolytic signaling events Includes chapter contributions from international leaders in the field
