Book Description
Protein Folding aims to collect the most important information in the field of protein folding and probes the main principles that govern formation of the three-dimensional structure of a protein from a nascent polypeptide chain, as well as how the functional properties appear. This text is organized into three sections and consists of 15 chapters. After an introductory chapter where the main problems of protein folding are considered at the cellular level in the context of protein biosynthesis, the discussion turns to the conformation of native globular proteins. Definitions and rules of nome ...

Book Description
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.

Book Description
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.

Book Description
The formation of disulphide bonds is probably the most influential modification of proteins. These bonds are unique among post-translational modifications of proteins as they can covalently link cysteine residues far apart in the primary sequence of a protein. This has the potential to convey stability to otherwise marginally stable structures of proteins. However, the reactivity of cysteines comes at a price: the potential to form incorrect disulphide bonds, interfere with folding, or even cause aggregation. An elaborate set of cellular machinery exists to catalyze and guide this process: facilitating bond formation, inhibiting unwanted pairings and scrutinizing the outcomes. Only in recent years has it become clear how intimately connected this cellular machinery is with protein folding helpers, organellar redox balance and cellular homeostasis as a whole. This book comprehensively covers the basic principles of disulphide bond formation in proteins and describes the enzymes involved in the correct oxidative folding of cysteine-containing proteins. The biotechnological and pharmaceutical relevance of proteins, their variants and synthetic replicates is continuously increasing. Consequently this book is an invaluable resource for protein chemists involved in realted research and production.

Book Description
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.

Book Description
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.
