Isozymes, II: Physiological Function contains manuscripts presented at the Third International Conference on isozymes convened in April 1974 at Yale University. Separating 53 manuscripts into chapters, this book first discusses the medical uses of isozymes. It then describes the various dehydrogenase isozymes mechanisms of action and biological functions. Other general topics explored are the roles of isozymes in adaptation to varying temperatures and their use in the study of mitochondria. Significant topics on specific isozymes are given separately in other chapters.

Cell Biology of Physarum and Didymium, Volume II: Differentiation, Metabolism, and Methodology summarizes important experimental research using Physarum and Didymium for developmental and cellular studies. This book is organized into three parts, encompassing 28 chapters that cover the differentiation, metabolism, and experimental techniques for cellular studies. After presenting an introduction to some aspects of developmental biology, this volume describes the ultrastructure and physiology of sporulation, spore germination, encystment, excystment, spherulation, and spherule germination. This is followed by a discussion on regulatory events leading to morphogenesis and on biochemical, physiological, and structural data on the amoeboid stage. The second part focuses on metabolic aspects. This includes metabolic characteristics of myxomycetes; the formation of nucleotides in Physarum by de novo synthesis and from nucleic acid degradation products; and radiation and radiomimetic agents on myxomycete species. Considerable chapters in the concluding part are devoted to procedures and protocol for isolation of cell components from Physarum and Didymium species. This volume also evaluates some techniques, including electron microscopy, time-lapse microcinematography, phase-contrast microscopy, Feulgen staining, and culture methods. The concluding chapters examine the preparation, isolation, and characterization of ribonucleic acid, histone, plasmodial polysaccharides, myosin, actins, and fragmin. The book will serve as a frequent, single reference source to brief cell biologists on the primary research on Physarum and Didymium. It will also be a good source for graduate students in cell biology and perhaps in other graduate courses.

This is now the fourth time that protein phosphorylation has been the focus of a NATO Advanced Study Institute. The first meeting with the topic "Signal Trans duction and Protein Phosphorylation" was held on the island of Spezai, Greece, in September 1986. The second one took place in Chateau La Londe, France, in September 1989 on "Cellular Regulation by Protein Phosphorylation", the third one on " Tyrosine Phosphorylation/Dephosphorylation and Downstream Signaling" was in September 1992 in Maratea, Italy. The titles of these books clearly mirror the developments that have taken place in the last decade. Beginning with the recognition that protein phosphorylation is at the center of signaling -clearly established in 1990 -it became apparent that many cellular processes are regulated by this mode. A new focus then emerged when it was recognized that growth factors are bound to corresponding receptors trigger protein tyrosine phosphorylation which controls cell prolifera tion. This was the topic of the third meeting in this series. It is now evident that further progress depends on understanding the three dimensional structure of the proteins involved. It goes without saying, for example, that understanding the location of proteins by adaptor proteins is only possible on the basis of the three dimensional protein structure. Therefore, the fourth meeting in this series concentrated on the protein structure of signaling molecules as well as on the elucidation of the principles of protein domain interactions.

Isozymes, I: Molecular Structure contains manuscripts presented at the Third International Conference on isozymes convened in April 1974 at Yale University. Separating 52 manuscripts into chapters, this book discusses the biology and biochemistry of isozymes. It also elucidates the multiple forms of mammalian DNA-dependent DNA polymerases, as well as RNA polymerases of maize, fungi, and Escherichia coli. Significant topics on some specific isozymes are given separately in other chapters.

The Springer Handbook of Enzymes provides concise data on some 5,000 enzymes sufficiently well characterized – and here is the second, updated edition. Their application in analytical, synthetic and biotechnology processes as well as in food industry, and for medicinal treatments is added. Data sheets are arranged in their EC-Number sequence. The new edition reflects considerable progress in enzymology: the total material has more than doubled, and the complete 2nd edition consists of 39 volumes plus Synonym Index. Starting in 2009, all newly classified enzymes are treated in Supplement Volumes.

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 "Enzyme Hand present book book" represents the printed version 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 all the numerous literature references for each enzyme (for special enzymes up to 40000) if the data representation is to be concise as is intended.
