Recent progress on enzyme immobilisation, enzyme production, coenzyme re generation and enzyme engineering has opened up fascinating new fields for the potential application of enzymes in a large range of different areas. As more progress in research and application of enzymes has been made the lack of an up-to-date overview of enzyme molecular properties has become more appar ent. Therefore, we started the development of an enzyme data information sys tem as part of protein-design activities at GBF. The present book "Enzyme Hand book" represents the printed vers ion of this data bank. In future a computer searchable version will be also available. The enzymes in this Handbook are arranged according to the Enzyme Com mission list of enzymes. Some 3000 "different" enzymes will be covered. Fre quently enzymes with very different properties are included under the same EC number. Although we intend to give a representative overview on the char acteristics and variability of each enzyme the Handbook is not a compendium. The reader will have to go to the primary literature for more detailed information. Naturally it is not possible to cover aII the numerous literature references for each enzyme (for special enzymes up to 40000) if the data representation is to be concise as is intended.

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.
