Chemical Approaches To The Synthesis Of Peptides And Proteins

Organic chemists working on the synthesis of natural products have long found a special challenge in the preparation of peptides and proteins. However, more reliable, more efficient synthetic preparation methods have been developed in recent years. This reference evaluates the most important synthesis methods available today, and also considers methods that show promise for future applications. This text describes the state of the art in efficient synthetic methods for the synthesis of both natural and artificial large peptide and protein molecules. Subjects include an introduction to basic topics, linear solid-phase synthesis of peptides, peptide synthesis in solution, convergent solid-phase synthesis, methods for the synthesis of branched peptides, formation of disulfide bridges, and more. The book emphasizes strategies and tactics that must be considered for the successful synthesis of peptides.

This book focuses on the chemical principles behind the more important methods of peptide synthesis, and it provides a critical, concise, and up-to-date survey of the field.

How to synthesize native and modified proteins in the test tube With contributions from a panel of experts representing a range of disciplines, Total Chemical Synthesis of Proteins presents a carefully curated collection of synthetic approaches and strategies for the total synthesis of native and modified proteins. Comprehensive in scope, this important reference explores the three main chemoselective ligation methods for assembling unprotected peptide segments, including native chemical ligation (NCL). It includes information on synthetic strategies for the complex polypeptides that constitute glycoproteins, sulfoproteins, and membrane proteins, as well as their characterization. In addition, important areas of application for total protein synthesis are detailed, such as protein crystallography, protein engineering, and biomedical research. The authors also discuss the synthetic challenges that remain to be addressed. This unmatched resource: Contains valuable insights from the pioneers in the field of chemical protein synthesis Presents proven synthetic approaches for a range of protein families Explores key applications of precisely controlled protein synthesis, including novel diagnostics and therapeutics Written for organic chemists, biochemists, biotechnologists, and molecular biologists, Total Chemical Synthesis of Proteins provides key knowledge for everyone venturing into the burgeoning field of protein design and synthetic biology.

This text is suitable for advanced undergraduate and beginning graduate students in chemistry and biochemistry studying amino acids and peptides. The authors concentrate on amino acids and peptides without detailed discussions of proteins, although the book gives all the essential background chemistry, including sequence determination, synthesis and spectroscopic methods, to enable the reader to appreciate protein behaviour at the molecular level. The approach is intended to encourage the reader to cross classical boundaries, as in the later chapters on the biological roles of amino acids and the design of peptide-based drugs. For example, there is a section on the enzyme-catalysed synthesis of peptides, with suitable examples, an area often neglected in texts describing peptide synthesis. This modern text will be of value in the amino acid, peptide and protein field, to advanced undergraduates, graduate students and research workers.

In the years since the publication of Atherton and Sheppard's volume, the technique of Fmoc solid-phase peptide synthesis has matured considerably and is now the standard approach for the routine production of peptides. The basic problems at the time of publication of this earlier work have now for the most part, been solved. As a result, innovators in the field have focussed their efforts to develop methodologies and chemistry for the synthesis of more complex structures. The focus of this new volume is much broader, and covers the essential procedures for the production of linear peptides and more advanced techniques for preparing cyclic, side-chain modified, phospho- and glycopeptides. Many other methods also deserving attention have been included: convergent peptide synthesis; peptide-protein conjugation; chemoselective ligation; and chemoselective purification. The difficult preparation of cysteine and methionine-containing peptides is also covered, as well as methods for overcoming aggregation during peptide chain assembly. Many of the techniques developed for the production of large arrays of peptides by parallel synthesis, such as t-bag, SPOT and PIN synthesis, have naturally been included. Finally, a survey of available automated instrumentation has also been provided.

In recent years, research has shown the importance of peptides in neuroscience, immunology, and cell biology. Active research programs worldwide are now engaged in developing peptide-based drugs and vaccines using modification of natural peptides and proteins, design of artificial peptides and peptide mimetics, and screening of peptide and phage libraries. In this comprehensive book, the authors discuss peptide synthesis and application within the context of their increasing importance to the pharmaceutical industry. Peptides: Synthesis, Structures, and Applications explores the broad growth of information in modern peptide synthetic methods and the structure-activity relationships of synthetic polypeptides. The history of peptide chemistry Amide formation, deprotection, and disulfide formation in peptide synthesis Solid-phase peptide synthesis a-helix formation by peptides in water Stability and dynamics of peptide conformation An overview of structure-function studies of peptide hormones Neuropeptides:peptide and nonpeptide analogs Reversible inhibitors of serine proteinases Design of polypeptides Current capabilities and future possibilities of soluble chemical combinatorial libraries Epitope mapping with peptides Synthesis and applications of branched peptides in immunological methods and vaccines

This volume provides updated protocols for chemical protein synthesis. Chapters guide readers through development methods, strategies, and applications of protein chemical synthesis. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols. Authoritative and cutting-edge, Chemical Protein Synthesis aims to be a useful and practical guide to new researchers and experts looking to expand their knowledge.

Encompassing all aspects of the structures of peptides and proteins, this book adopts a uniquely problem-oriented approach to the topic. Starting with a look at the structures and properties of the twenty amino acids that occur in proteins, and moving on to the synthesis of polypeptides and the isolation of proteins, Peptides and Proteins then addresses the methods of analysis of protein characteristics, including the modern methods of sequence analysis by mass spectrometry. Further chapters examine the three-dimensional nature of protein structure, and introduce the student to the use of computer applications (molecular graphics, databases, bioinformatics) in protein chemistry. Original research data is used in many of the problems, and throughout sufficient background biology is included, thus putting the subject into context for chemists. Aimed at first and second-year chemistry students, this title will also be of interest to students of biochemistry. Ideal for the needs of undergraduate chemistry students, Tutorial Chemistry Texts is a major new series consisting of short, single topic or modular texts concentrating on the fundamental areas of chemistry taught in undergraduate science courses. Each book provides a concise account of the basic principles underlying a given subject, embodying an independent-learning philosophy and including worked examples.
