Available in PDF, EPUB and Kindle. Book excerpt: 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 or read book Uptake and Trafficking of Protein Toxins written by Holger Barth and published by Springer. This book was released on 2017-12-01 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the transport of medically relevant bacterial protein toxins into mammalian cells, and on novel pharmacological strategies to inhibit toxin uptake. The first chapters review our current understanding of the cell-surface receptors and cellular transport processes of Clostridium botulinum neurotoxins, Clostridium botulinum C3 toxin, Clostridium difficile toxins, binary clostridial enterotoxins, anthrax toxins and diphtheria toxin. In brief, specific binding/transport (B) subunits deliver the enzyme (A) subunits into the cytosol, where the latter modify their substrates, producing cytotoxic effects and the characteristic toxin-associated diseases. Key mechanisms for the transport of the A subunits from endosomes into the cytosol and the role of trans-membrane pores formed by the B subunits and host cell chaperones for this process are reviewed. The book’s closing chapters focus on compounds which inhibit the transport of the A subunits from endosomes into the cytosol and therefore might lead to novel therapeutic strategies for toxin-associated diseases. These substances include pharmacological inhibitors of the host cell chaperones involved, as well as multivalent and heterocyclic molecules that specifically block the toxins’ translocation channels. This volume offers an up-to-date resource for scientists.

Download or read book Molecular Action of Toxins and Viruses written by P. Cohen and published by Elsevier. This book was released on 2012-12-02 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Action of Toxins and Viruses investigates the molecular action of bacterial toxins and viruses and its striking similarity to the mechanisms by which many neural and hormonal stimuli control normal cell functions. Topics covered include the biological activity of diphteria toxin; the role of cholera toxin in the regulation of hormone-sensitive adenylate cyclase; toxic lectins and related proteins; and bacterial cytolysins (membrane-damaging toxins). Comprised of nine chapters, this volume begins with a discussion on the biosynthesis and biological activity of diphtheria toxin, toxin-resistant mutant cells, and the entry of toxin into cells and fragment A in the cytoplasm of living cells. The reader is then systematically introduced to the use of cholera toxin as a probe to study the regulation and interaction of adenylate cyclase components; the toxic action of lectins and related proteins such as abrin, ricin, and modeccin; and the ability of bacterial cytolysins to damage cell membranes. The remaining chapters focus on the mechanism of action of colicin E2, colicin E3, and cloacin DF13; similarities in the action of different bacterial toxins; the role of cell membranes in infection with bacterial viruses and colicins; and the life cycle and infection mechanisms of bacteriophage T4. The book concludes with an analysis of the involvement of protein kinases in viral transformation. This monograph will be of interest to students, practitioners, and researchers in fields ranging from molecular biology and biochemistry to cell biology, bacteriology, and physiology.
