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.

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.

Enzymes, which work as organic catalysts for chemical reactions, are of interest to a wide range of scientific disciplines. The Source Book of Enzymes provides a worldwide listing of commercially available enzymes, offering the widest possible selection of enzyme products for specific applications. The Source Book of Enzymes answers these important questions and many more: Where can I find a particular enzyme? What enzymes are available for purchase? How do I select the appropriate enzyme for my application? How do the available enzymes differ from one another? What are the reaction conditions for optimum enzyme performance? Who sells the enzyme I need? The reliable research tool you will turn to again and again With the Source Book of Enzymes you will save hours of research time once wasted on searching through catalogs and product data bulletins. This practical reference tool makes the selection process easy by providing systematic and comparative functional information about each enzyme. Its global scope ensures that you will find the enzyme and supplier most suited to your needs and geographical location. Students and educators; researchers in academia, industry and government; bioengineers and biotechnologists, and purchasing agents will find this an invaluable resource for conducting competitive assessments, identifying new product trends and opportunities, identifying enzyme properties, and ordering specific enzymes.

In recent years, there have been considerable developments in techniques for the investigation and utilisation of enzymes. With the assistance of a co-author, this popular student textbook has been updated to include techniques such as membrane chromatography, aqueous phase partitioning, engineering recombinant proteins for purification and due to the rapid advances in bioinformatics/proteomics, a discussion of the analysis of complex protein mixtures by 2D-electrophoresis and RPHPLC prior to sequencing by mass spectroscopy. Written with the student firmly in mind, no previous knowledge of biochemistry, and little of chemistry, is assumed. It is intended to provide an introduction to enzymology, and a balanced account of all the various theoretical and applied aspects of the subject which are likely to be included in a course.
