the refolding process is often the critical bottleneck in the production of high-value proteins, and recently acquired insights have yet to be translated into technological advantages. These proceedings bridge the gap between fundamental and applied studies, addressing such issues as in vivo protein folding, protein aggregation and inclusion body formation, elucidation of the folding pathway, characterization of folding intermediates, and practical considerations in protein renaturation. The symposium was part of the 199th ACS National Meeting, Boston, April 1990. Annotation copyrighted by Book News, Inc., Portland, OR

Discusses the molecular mechanisms controlling protein folding in vivo and in vitro.

Proteins are one of the most basic components of all living cells and therefore serve a vital purpose in the cells of animals, plants and bacteria. They are comprised of chains of amino acids, which are held together by ribosome. These chains have many different patterns, which are known as `folds.' These folds are complicated, and therefore susceptible to irregularities that are known to be the source of many diseases. Cystic fibrosis, mad cow disease, Alzheimer's disease, emphysema and others are all initiated by improper protein folds. It is clear that, improving our understanding of protein folding is a key to fighting these diseases. This book presents recently performed research from around the world on this important subject.

This volume provides comprehensive protocols on experimental and computational methods that are used to study probe protein folding reactions and mechanisms. Chapters divided into five parts detail protein engineering, protein chemistry, experimental approaches to investigate the thermodynamics and kinetics of protein folding transitions, probe protein folding at the single molecule, analysis and interpretation of computer simulations, procedures and tools for the prediction of protein folding properties. 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, Protein Folding: Methods and Protocols aims to be a useful practical guide to researches to help further their study in this field.

This book covers the fundamentals of protein inactivation during bioseparation and the effect on protein processing. Bioseparation of Proteins is unique because it provides a background of the bioseparation processes, and it is the first book available to emphasize the influence of the different bioseparation processes on protein inactivation. Bioseparation of Proteins covers the extent, mechanisms of, and control of protein inactivation during these processes along with the subsequent and essential validation of these processes. The book focuses on the avoidance of protein (biologicalproduct) inactivation at each step in a bioprocess. It compares protein inactivation exhibited during the different bioseparation processes by different workers and provides a valuable framework for workers in different areas interested in bioseparations. Topics include separation and detection methods; estimates of protein inactivation and an analysis of this problem for different separation processes; strategies for avoiding inactivation; the molecular basis of surface activity and protein adsorption,process monitoring, and product validation techniques; and the economics of various bioseparation processes and quality control procedures. Key Features * Protein inactivation and other aspects of biological stability are critical to an effective bioseparation process; This book is a detailed and critical review of the available literature in an area that is essential to the effectiveness, validation, and economics of bioseparation processes for drugs and other biological products; Conveniently assembled under one cover, the survey of the literature and resulting perspective will greatly assist engineers and chemists in designingand improving their own processes; Key features of the text include: * detailed data on biological stability under various bioseparation conditions * extensive case studies from the literature on separation processes, validation, and economics * simplified analysis of protein refolding and inactivation mechanisms * consideration of adsorption theories and the effect of heterogeneity * coverage of both classical and novel bioseparation techniques, including chromatographic procedures

The book will discuss classes of proteins and their folding, as well as the involvement of bioinformatics in solving the protein folding problem. In vivo and in vitro folding mechanisms are examined, as well as the failures of in vitro folding, a mechanism helpful in understanding disease caused by misfolding. The role of energy landscapes is also discussed and the computational approaches to these landscapes.
