Download or read book Gamma Glutamyl Transpeptidases written by Immacolata Castellano and published by Springer Science & Business Media. This book was released on 2013-07-09 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamma-Glutamyl Transpeptidases (γ-GTs) are members of the N-terminal nucleophile hydrolase superfamily, enzymes that cleave the γ-glutamyl amide bond of glutathione to liberate cysteinylglycine. The released γ-glutamyl group can be transferred to water (hydrolysis) or to amino acids or short peptides (transpeptidation). γ-GT plays a key role in the gamma glutamyl cycle by regulating the cellular levels of the antioxidant glutathione, hence it is a critical enzyme in maintaining cellular redox homeostasis.γ-GT is upregulated during inflammation and in several human tumors, and it is involved in many physiological disorders related to oxidative stress, such as Parkinson’s disease and diabetes. Furthermore, this enzyme is used as a marker of liver disease and cancer. This book covers current knowledge about the structure-function relationship of γ-GTs and gives information about applications of γ-GTs in different fields ranging from clinical biochemistry to biotechnology and biomedicine.
Download or read book Functions of Glutathione in Liver and Kidney written by H. Sies and published by Springer. This book was released on 2011-11-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The serene phrase, Lest I forget thee, glutathione ... , coined by the Kosowers (1) to describe the state in the 1960's, must be replaced now by something like "Inevitable GSH" in order to characterize the current situation. The surge in interest on the ubiquitous tripeptide has been ama zing, with publications on GSH running at rates as high as one per day, so that it seemed appropriate to convene international experts for a discussion of recent develop ments this year. Unlike the two previous meetings in this decade held in Tlibingen in 1973 (2) and in santa Ynez in 1975 (3), the scope was restricted to Functions of Gluta thione in Liver and Kidney. Only in this way did an in-depth discussion of the current state of knowledge in a limit ed topic appear possible. The last couple of years have seen a fascinating pro ductivity in the fields of (a) Regulation of the Glutathione Level in the Liver, (b) Role of y-Glutamyltransferase in Gluta thione Turnover with emphasis on the renal enzyme, and a critical appraisal of the y-Glutamyl Cycle, (c) Hyd:roperox ide and Disulfide Metaholism, enriched by the discovery of the nonseleniurn-dependent glutathione peroxidase activ ity and its relation to the glutathione-S-transferases, and the participation of the 2GSH/GSSG system in redox transitions in intact organ, cells and isolated mito chondria, and (d) a multitude of Pharmacological and Toxi cological Aspects related to glutathione, mainly centered on the events leading to liver damage and the protective

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Download or read book Amino Acid Homopolymers Occurring in Nature written by Yoshimitsu Hamano and published by Springer Science & Business Media. This book was released on 2010-07-30 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microorganisms are capable of producing a wide variety of biopolymers. Homopolymer peptides, which are made up of only a single type of amino acid, are far less ubiquitous. The only two amino-acid homopolymers known to occur in nature are presented in this volume. Poly-epsilon-L-lysine is a polycationic peptide and exhibits antimicrobial activity against a wide spectrum of microorganisms. It is both safe and biodegradable and is therefore used as a food preservative in several countries. In addition, there has been great interest in medical and other applications of poly-lysine and its derivatives. In contrast, poly-gamma-glutamic acid is an unusual anionic polypeptide. It is also water soluble, biodegradable, edible, non-toxic and non-immunogenic and can be chemically modified to introduce various drugs. These features are very useful for pharmaceutical and biomedical applications. Poly-glutamic acid is also a highly attractive as a food ingredient.

Download or read book Biological Reactive Intermediates III written by James J. Kocsis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1028 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the third in a series of conferences entitled, The International Symposium on Biological Reactive Intermediates. The first was held at the University of Turku in Finland, in 1975, the second at the University of Surrey in the United Kingdom, in 1980 and the most recent at the University of Maryland in the United States, in 1985. The significance of these conferences has been emphasized by the rapid growth of mechanistic toxicology over the last decade. These conferences were initially stimulated by the attempt to uncover the significance behind the observations that the toxicity of carcinogenic responses produced by many chemicals was associated with the observation that their metabolism led to the formation of chemcially reactive electrophiles which covalently bound to nucleophilic sites in cells such as proteins, nucleic acid or fats. Recently, newer concepts have arisen which have necessitated the expansion of subjects covered by the conference. For example, the application of newer knowledge of the role of active oxygen species in reactive metabolite formation, the concept of suicide substrates, examination of the function of glutathione in cells, application of immunological techniques and molecular biological probes to the solution of toxicological problems all had an impact on the study of the biological reactive intermediates.

Download or read book Active Site directed Enzyme Inhibitors written by Weiping Zheng and published by Royal Society of Chemistry. This book was released on 2023-09-13 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our biological system is enriched with enzyme-catalyzed (or enzymatic) reactions that mediate a great multitude of life processes such as gene transcription and metabolism, and the inappropriately up-regulated activity of these enzymatic reactions is a major cause of human diseases such as cancer and metabolic diseases. Therefore, the inhibitors of enzymatic reactions (generally called enzyme inhibitors) constitute a major class of therapeutic agents on the global drug market. One question would then be how to efficiently design enzyme inhibitors. This handbook is the first of its kind in the field, introducing to its readers in a single book the concepts whose exploitation has been demonstrated to be successful in efficiently furnishing effective active site-directed inhibitors for various enzymatic reactions. The book is organized by different concepts and for each concept there is a delineation of its mode of working and its applications with different types of enzymatic reactions. Active Site-directed Enzyme Inhibitors will help its readers to quickly and efficiently obtain effective active site-directed inhibitors for any of the enzymatic reactions under study without a need to resort to library screening- and biostructure-based techniques. This handbook is ideal as an immediate resource for researchers to consult or for students to supplement their study in medicinal chemistry and related courses.
