DOWNLOAD EBOOK →ADP-ribosylating toxins have been the focus of intensive research for more than 30 years. Researchers from diverse fields of science have taken an interest in these bacterial toxins; they are studied, for example, by microbiologists, biochemists, cell biologists, and pharmacologists. There are two principal reasons for the broad and still growing interest in ADP ribosylating toxins. First, insights into the structure and functions of the toxins might be the key to prevention and treatment of diseases caused by the toxin-producing infectious micro organisms. Second, the ADP-ribosylating toxins provide potent and often unique pharmacological tools for the study of the physiological functions of their target proteins. The latter is especially the case with cholera and pertussis toxins, which both modify the IX-subunits of heterotrimeric G-proteins involved in signal transduction pathways. These toxins have proved invaluable in extending our basic understanding of the regulation of hormone-controlled signal transduction. This volume provides a review and an update of recent studies on the basic properties of bacterial ADP-ribosylating tbxins and/or exoenzymes. Our current knowledge of the cel lular entry mechanisms of ADP-ribosylating toxins is reviewed by MADSHUS and STENMARK. WILSON and COLLIER then deal with recent insights into the enzyme mechanism and active site structure of diphtheria toxin and Pseudomonas aeruginosa exotoxin A, which modify elongation factor 2. Toxins which ADP-ribosylate heterotrimeric G-proteins involved in trans membrane signal transduction are the subject of the next two chapters.

DOWNLOAD EBOOK →This volume gathers the latest exciting findings on ADP-ribosylation from renowned experts in the field. It includes ten chapters, organized into the following three thematic sections: · Evolution and detection of endogenous ADP-ribosylation · ADP-ribosylation by the ARTC family of ADP-ribosyltransferases (R-S-E ARTs) · ADP-ribosylation by the ARTD family of ADP-ribosyltransferases (H-Y-E ARTs) The book will provide readers a better understanding of ADP-ribosylating toxins and their endogenous relatives. This provides a basis for developing novel toxin-neutralizing drugs and drugs targeting endogenous ADP-ribosyltransferase relatives.

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →Of the multitude of toxins known and the enormous variety of effects they cause, of particular interest are those that influence signal transduction. Intercellular communication by chemical signals is essential for the functioning of multicellular organisms. Many toxins exert their biological effects by interfering with the signal transduction initiated by these chemicals (hormones, transmitters, growth factors, and other mediators). Up-to-date information is provided by outstanding experts, who discuss the molecular mechanisms involved in the action of many toxins, as well as the use of toxins as informative tools with which to study signal transduction and their potential therapeutic usage. This volume contains useful information for the experimentalist interested in toxins or in signal transduction, as well as for the reader interested in gaining a comprehensive overview of the field. The Cellular and Molecular Mechanisms of Toxin Action series will include monographs on signal transduction, secretory systems, cytoskeleton, selective neurotoxicity of natural, recombinant and chimeric toxins giving a broader emphasis on the mechanism of action, structure-function relationship, and use of toxins as research tools and their therapeutic applications.
