Protein Actions

Protein Actions: Principles and Modeling is aimed at graduates, advanced undergraduates, and any professional who seeks an introduction to the biological, chemical, and physical properties of proteins. Broadly accessible to biophysicists and biochemists, it will be particularly useful to student and professional structural biologists and molecular biophysicists, bioinformaticians and computational biologists, biological chemists (particularly drug designers) and molecular bioengineers. The book begins by introducing the basic principles of protein structure and function. Some readers will be familiar with aspects of this, but the authors build up a more quantitative approach than their competitors. Emphasizing concepts and theory rather than experimental techniques, the book shows how proteins can be analyzed using the disciplines of elementary statistical mechanics, energetics, and kinetics. These chapters illuminate how proteins attain biologically active states and the properties of those states. The book ends with a synopsis the roles of computational biology and bioinformatics in protein science.

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.

In recent years remarkable progress has been accomplished with respect to our knowledge about bacterial protein toxins. This refers especially to structural aspects of protein toxins but also holds true for genetics, molecular biology and biochemical mechanisms underlying the action of toxins. This volume covers the very current and exciting aspects of up-to-date bacterial toxicology and comprehensively reviews the most important bacterial protein toxins such as the intracellular acting toxins which exhibit enzyme activity, as well as those toxins that interact with cell plasma membranes by damaging the membranes (pore formation) or stimulating cell receptors (superantigens). This is the most current reference work on these important bacterial protein toxins, which are presented from the point of view of different disciplines such as pharmacology, microbiology, cell biology and protein chemistry.

The family of IGFBPs has been developed by the duplication of genes and genomes and contributes to genetic and functional diversity. Due to the different protein domains present in the molecule, IGFBPs can be seen as mediators of tissue-specific IGF-functions. However, IGFBPs also have IGF-independent functions both inside and outside the cell. These diverse genetic, molecular and functional aspects of IGFBPs are discussed within this Research Topic. Accumulating data provide evidence for the regulation of IGFBP-functions by proteases, which may acutely regulate bioactivity of the IGFs. However, during proteolytic degradation IGFBP-fragments with novel functions can also be formed and are located both intra- and extracellularly. Distinct IGFBP-fragments can even be found in the perinuclear compartment or within the nucleus, where they can impact on gene expression. Several contributions presented in the current Research Topic particularly stress the relevance of structural aspects in IGFBP research. The current lack of comprehensive structural information is dramatically limiting the biomarker potential of particular IGFBPs. Finally, the Research Topic also provides novel functions of the IGFBP family from model organisms, farm animals and humans. Thereby, the biomarker potential not only relates to normal and malignant growth but also to metabolism and animal welfare. One important aim of the Research Topic is to encourage next generation IGFBP research reflecting subject-individual, conditional, and hormonal parameters but also structural aspects of the IGFBPs.

The book Heat Shock Protein-Based Therapies provides the most up-to-date review on new heat shock protein-based mechanisms used in the therapy and treatment of various human disorders and diseases, including cancer, muscular atrophy, neurodegenerative disorders (Alzheimer's Disease, Multiple Sclerosis) and infectious diseases (HIV, periodontal disease). Written by leaders in the field of heat shock protein research, the chapters systematically and in a step wise fashion takes the reader through the fascinating sequence of events by which mechanisms dependent on heat shock proteins are targeted. The chapters also provide answers as to HSP biological significance to the host. This book is a must read for graduate and postgraduates in the field of Drug Development, Biotechnology, Pharmaceutical Industry, Phytomedicine, Biology (plant and mammal), Biochemistry (pro- and eukaryotic), Oncology, Immunology, Microbiology, Exercise Medicine, Physiology, Inflammatory diseases, Autoimmunity, Pharmacology and Pathology.

New textbooks at all levels of chemistry appear with great regularity. Some fields like basic biochemistry, organic reaction mechanisms, and chemical thermodynamics are well represented by many excellent texts, and new or revised editions are published sufficiently often to keep up with progress in research. However, some areas of chemistry, especially many of those taught at the graduate level, suffer from a real lack of up-to-date textbooks. The most serious needs occur in fields that are rapidly changing. Textbooks in these subjects usually have to be written by scientists actually involved in the research which is advancing the field. It is not often easy to persuade such individuals to set time aside to help spread the knowledge they have accumulated. Our goal, in this series, is to pinpoint areas of chemistry where recent progress has outpaced what is covered in any available textbooks, and then seek out and persuade experts in these fields to produce relatively concise but instructive introductions to their fields. These should serve the needs of one semester or one quarter graduate courses in chemistry and biochemistry. In some cases the availability of texts in active research areas should help stimulate the creation of new courses.
