This is the second of five books in the Amino Acids, Peptides and Proteins in Organic Synthesis series.   Closing a gap in the literature, this is the only book series in 5 volumes to cover this important topic in organic and biochemistry. Drawing upon the combined expertise of the international "who's who" in amino acid research, this series is a real benchmark for amino acid chemistry, providing a comprehensive discussion of the occurrence, uses and applications of amino acids and, by extension, their polymeric forms, peptides and proteins. The practical value of each volume is heightened by the inclusion of experimental procedures.   Clearly structured in three main sections, this second volume in the series begins with the synthesis and chemistry of modified amino acids. The second part deals with the catalysis of reactions by amino acids, while the final section is devoted to enzymes, including proteases as catalysts, semisynthetic enzymes, catalysis by peptide-based enzyme models, substrate and protein recognition, as well as mammalian and insect peptide hormones. Diese stark praxisbezogene Reihe in 5 Bänden schließt eine Lücke in der verfügbaren Fachliteratur. Alle international wichtigen Aminosäureforscher diskutieren hier Vorkommen, Verwendungsmöglichkeiten und bereits existierende Anwendungen von Aminosäuren und ihren Polymeren, Peptiden und Proteinen.
