This unique volume reviews the beautiful architectures and varying mechanical actions of the set of specialized cellular proteins called molecular chaperones, which provide essential kinetic assistance to processes of protein folding and unfolding in the cell. Ranging from multisubunit ring-shaped chaperonin and Hsp100 machines that use their central cavities to bind and compartmentalize action on proteins, to machines that use other topologies of recognition — binding cellular proteins in an archway or at the surface of a 'clamp' or at the surface of a globular assembly — the structures show us the ways and means the cell has devised to assist its major effectors, proteins, to reach and maintain their unique active forms, as well as, when required, to disrupt protein structure in order to remodel or degrade. Each type of chaperone is beautifully illustrated by X-ray and EM structure determinations at near- atomic level resolution and described by a leader in the study of the respective family. The beauty of what Mother Nature has devised to accomplish essential assisting actions for proteins in vivo is fully appreciable.

The first of its kind, this volume presents the latest research findings on the chaperonins, the best studied family of a class of proteins known as molecular chaperones. These findings are changing our view of some fundamental cellular processes involving proteins, especially how proteins fold into their functional conformations. - Origins of the new view of protein folding - Prokaryotic chaperonins - Eukaryotic chaperonins - Evolution of the chaperonins - Refolding of denatured proteins - Organelle biosynthesis - Biomedical aspects

This book serves as an introduction to protein structure and function. Starting with their makeup from simple building blocks, called amino acids, the 3-dimensional structure of proteins is explained. This leads to a discussion how misfolding of proteins causes diseases like cancer, various encephalopathies, or diabetes. Enzymology and modern concepts of enzyme kinetics are then introduced, taking into account the physiological, pharmacological and medical significance of this often neglected topic. This is followed by thorough coverage of hæmoglobin and myoglobin, immunoproteins, motor proteins and movement, cell-cell interactions, molecular chaperones and chaperonins, transport of proteins to various cell compartments and solute transport across biological membranes. Proteins in the laboratory are also covered, including a detailed description of the purification and determination of proteins, as well as their characterisation for size and shape, structure and molecular interactions. The book emphasises the link between protein structure, physiological function and medical significance. This book can be used for graduate and advanced undergraduate classes covering protein structure and function and as an introductory text for researchers in protein biochemistry, molecular and cell biology, chemistry, biophysics, biomedicine and related courses. About the author: Dr. Buxbaum is a biochemist with interest in enzymology and protein science. He has been working on the biochemistry of membrane transport proteins for nearly thirty years and has taught courses in biochemistry and biomedicine at several universities.

The precise shape of a protein is a crucial factor in its function. How do proteins become folded into the right conformation? Molecular chaperones and protein folding catalysts bind to developing polypeptides in the cytoplasm and ensure correct folding and transport. This Guidebook catalogues the latest information on nearly 200 of these molecules, including the important class of heat shock proteins; each entry is written by leading researchers in the field.

This book will deal with heat shock proteins and more generally with stress-related inducible gene expression as a pleiotropic adaptive response to stress. It presents a textbook-like overview of the field not only to heat shock experts, but to physiologists, pharmacologists, physicians, neuropsychologists and others as well. It is intended to be a state-of-the-art and perspective book rather than an up-to-date presentation of recent data. It should provide a basis for new experimental approaches to fields at the edge of the classical heat shock field. Drugs, UV irradiation and environmental toxics will considered as important modulators of the stress response. Radical scavengers such as superoxide dismutases and inducible regulatory proteins of metallic ion status such as ferritin as well as immunophilins and protein disulfide isomerases will be considered within the frame of stress proteins. The potential practical applications of heat shock proteins in toxicology and medicine for the diagnosis, prognosis and eventually therapy of clinical conditions associated with an increased oxidative burden will be outlined. The role of heat shock proteins in the modulation of immune responses will also be included. The book considers heat shock from a broad perspective including fields for which heat-shock may become of importance in the very near future such as cellular responses to environmental stresses and complex stress responses under specific conditions. It was also felt timely to incorporate a whole section on medical and technological applications of stress proteins.

Understanding abiotic stress responses in plants is critical for the development of new varieties of crops, which are better adapted to harsh climate conditions. The new book by the well-known editor team Narendra Tuteja and Sarvajeet Gill provides a comprehensive overview on the molecular basis of plant responses to external stress like drought or heavy metals, to aid in the engineering of stress resistant crops. After a general introduction into the topic, the following sections deal with specific signaling pathways mediating plant stress response. The last part covers translational plant physiology, describing several examples of the development of more stress-resistant crop varieties.

Molecular chaperones are involved in a wide variety of essential cellular processes in living cells. A subset of molecular chaperones have been initially described as heat shock proteins protecting cells from stress damage by keeping cellular proteins in a folding competent state and preventing them from irreversible aggregation. Later it became obvious that molecular chaperones are also expressed constitutively in the cell and are involved in complex processes such as protein synthesis, intracellular protein transport, post-translational modification and secretion of proteins as well as receptor signalling. Hence, it is not surprising that molecular chaperones are implicated in the pathogenesis of many relevant diseases and could be regarded as potential pharmacological targets. Starting with the analysis of the mode of action of chaperones at the molecular, cellular and organismic level, this book will then describe specific aspects where modulation of chaperone action could be of pharmacological and therapeutic interest.

This book reviews understanding of the biological roles of extracellular molecular chaperones. It provides an overview of the structure and function of molecular chaperones, their role in the cellular response to stress and their disposition within the cell. It also questions the basic paradigm of molecular chaperone biology - that these proteins are first and foremost protein-folding molecules. Paradigms of protein secretion are reviewed and the evolving concept of proteins (such as molecular chaperones) as multi-functional molecules for which the term 'moonlighting proteins' has been introduced is discussed. The role of exogenous molecular chaperones as cell regulators is examined and the physiological and pathophysiological role that molecular chaperones play is described. In the final section, the potential therapeutic use of molecular chaperones is described and the final chapter asks the question - what does the future hold for the extracellular biology of molecular chaperones?

This volume of Advances in Protein Chemistry provides a broad, yet deep look at the cellular components that assist protein folding in the cell. This area of research is relatively new--10 years ago these components were barely recognized, so this book is a particularly timely compilation of current information. Topics covered include a review of the structure and mechanism of the major chaperone components, prion formation in yeast, and the use of microarrays in studying stress response. Outlines preceding each chapter allow the reader to quickly access the subjects of greatest interest. The information presented in this book should appeal to biochemists, cell biologists, and structural biologists.
