The Proteasome — Ubiquitin Protein Degradation Pathway
This volume gives an overview of pro tea some-mediated protein degradation and the regulatory role of the ubiquitin system in cellular proteolysis. The first chapter describes the molecular evolution of the proteasome and its associated activators, i. e. , the 20S core, the base and the lid of the 19S cap, and the 11 S regulator. The ensuing chapter gives an overview of the structure and assembly of the 20S proteasome and the regulation of the archaeal proteasome by PAN. The third contribution summarizes our knowledge on the eukaryotic 26S proteasome and its regulation by the 19S regu lator, followed by a chapter devoted to the llS regulator, which elucidates the structural basis for the 11 ...
The Ubiquitin-Proteasome System
The second volume in a new series dedicated to protein degradation, this book discusses the mechanism and cellular functions of targeted protein breakdown via the ubiquitin pathway. Drawing on the combined knowledge of the world's leading protein degradation experts, this handy reference compiles information on the proteasome-mediated degradation steps of the ubiquitin pathway. In addition to proteasomal function and regulation, it also presents the latest results on novel members of the ubiquitin superfamily and their role in cellular regulation. Further volumes in the series cover the function of ubiquitin-protein ligases, and the roles of the ubiquitin pathway in regulating key cellular processes, as well as its pathophysiological disease states. Required reading for molecular biologists, cell biologists and physiologists with an interest in protein degradation.
Protein Folding in the Cell
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.
Co- and Posttranslational Proteolysis of Proteins
This volume examines a number of different proteases, a type of enzyme, that are required in order for the change to a biologically active mature protein to occur. The discussion of these various proteases is rarely undertaken in one volume and will serve as a great resource for scientists studying the group of proteases on signal peptide processing as well as those working on propeptide processing. These areas of research do not normally overlap, and yet they are each of common importance to the same cell processes.
The Ubiquitin-proteasome Proteolytic System
Ubiquitin-proteasome-dependent proteolysis is central to an incredible multitude of processes in all eukaryotes, including the cell cycle, cell growth and differentiation, embryogenesis, apoptosis, signal transduction, DNA repair, regulation of transcription and DNA replication, transmembrane transport, endocytosis, stress responses, antigen presentation and other aspects of the immune response, the functions of the nervous system including circadian rhythms, axon guidance and acquisition of memory.This book tells the story of the ubiquitin system as we currently know it: from the regulation of basic cellular processes to quality control and the pathogenetic mechanisms of disease, from X-ray crystallography of the 26S proteasome to the interaction between substrates and their ligases, to the development of mechanism-based drugs, and to target-specific aberrant processes.

The New Foundations of Evolution
This is the story of a profound revolution in the way biologists explore life's history, understand its evolutionary processes, and reveal its diversity. It is about life's smallest entities, deepest diversity, and greatest cellular biomass: the microbiosphere. Jan Sapp introduces us to a new field of evolutionary biology and a new brand of molecular evolutionists who descend to the foundations of evolution on Earth to explore the origins of the genetic system and the primary life forms from which all others have emerged. In so doing, he examines-from Lamarck to the present-the means of pursuing the evolution of complexity, and of depicting the greatest differences among organisms. The New F...
Bacterial Virulence Factors and Rho GTPases
Pathogenic bacteria for human and animals have developed sophisticated weapons, termed virulence factors, to ensure their replication and persistence into their hosts. The authors in this volume show a synthesis on how the various host cellular Rho GTPases activities are manipulated by bacteria to fulfil their virulence.
