Structure And Action Of Molecular Chaperones: Machines That Assist Protein Folding In The Cell


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.

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




Abiotic Stress Response in Plants


Book Description

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.




Fundamentals of Protein Structure and Function


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.




Molecular Aspects of the Stress Response: Chaperones, Membranes and Networks


Book Description

This book makes a novel synthesis of the molecular aspects of the stress response and long term adaptation processes with the system biology approach of biological networks. Authored by an exciting mixture of top experts and young rising stars, it provides a comprehensive summary of the field and identifies future trends.




Protein Folding in the Cell


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.




The Molecular Chaperones Interaction Networks in Protein Folding and Degradation


Book Description

Molecular chaperones are a fundamental group of proteins that have been identified only relatively recently. They are key components of a protein quality machinery in the cell which insures that the folding process of any newly-synthesized polypeptide chain results in the formation of a properly folded protein and that the folded protein is maintained in an active conformation throughout its functional lifetime. Molecular chaperones have been shown to play essential roles in cell viability under both normal and stress conditions. Chaperones can also assist in the unfolding and degradation of misfolded proteins and in disaggregating preformed protein aggregates. Chaperones are also involved in other cellular functions including protein translocation across membranes, vesicle fusion events, and protein secretion. In recent years, tremendous advances have been made in our understanding of the biology, biochemistry, and biophysics of function of molecular chaperones. In addition, recent technical developments in the fields of proteomics and genomics allowed us to obtain a global view of chaperone interaction networks. Finally, there is now a growing interest in the role of molecular chaperones in diseases. This book will provide a comprehensive analysis of the structure and function of the diverse systems of molecular chaperones and their role in cell stress responses and in diseases from a global network perspective. ​
