Download or read book Handbook of ATPases written by Masamitsu Futai and published by John Wiley & Sons. This book was released on 2006-01-24 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: ATP-dependent active ion transport enables cells to regulate their pH value and to control their ion composition. The reverse process, transforming an ion imbalance into chemical energy, drives mitochondrial and chloroplast ATP synthesis. The mediators of these fundamental processes are ion-motive ATPases, highly conserved enzymes that play key roles in cell physiology from bacteria to man. As the first comprehensive overview of this important class of enzymes, this handbook summarizes recent knowledge about the molecular mechanism of ATPases, relating this information to the physiology and pathopyhsiology of ion transport, mitochondrial function, vesicle transport and lysosomal acidification. All important P-type, F-type and V-type ATPases are treated systematically, complemented by a special section on the cell biology and physiology of acidic compartments, and backed by an extensive bibliography and index. This premier reference source for physiologists, molecular biologists, biophysicists and clinical researchers contains contributions by the world's foremost ATPase research groups.

Download or read book ATPases written by A.G. Lee and published by Elsevier. This book was released on 1996-12-17 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 5 of Biomembranes covers an important group of membrane proteins, the ATPases. The P-type ATPases couple the hydrolysis of ATP to the movement of ions across a membrane and are characterized by the formation of a phosphoyrlated intermediate. Included are the plasma membrane and muscle sarcoplasmic reticulum Ca2+ -ATPases, the (Na+ -K+) -ATPase, the gastric (H+ -K+) -ATPase, the plasma membrane H+ -ATPase of fungi and plants, the Mg2+ - transport ATPase, the Salmonella typhimurium, and the K+ -ATPase of Escherichia coli, KdpB. The other important classes of ATPase in eukaryotic systems are the vacuolar H+ -ATPases and the F0F1 ATP synthase, and, in bacteria, the anion-translocating ATPases, responsible for resistance to arsenicals and antimonials, and the (Na+ -Mg2+) -ATPase of Acholeplasma. Finally, eukaryotic systems contain a variety of ectonucleotidases important, for example, in hydrolysis of extracellular ATP released as a cotransmitter from cholinergic and adrenergic nerve terminals. Volume 5 of Biomembranes explores structure-function relationships for these mebrane-bound ATPases.

Download or read book Organellar Proton ATPases written by Nathan Nelson and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE WORLD OF PROTON PUMPS Nathan Nelson uite frequently an observer looks at a life phenomenon and asks ~himself why nature took this route out of several other available mec anisms. In order to understand this challenge he may first try to reconstruct the evolution of the process taking into account the main driving forces that were assumed to exist during the last 3. 5 billion years on earth. Now we know that the electrochemical gradient of protons is the universal high-energy intermediate produced and uti lized by every living cell in nature. This high energy intermediate is an expression of different concentrations of active protons in the two faces of biological membranes. Why then did nature elect to utilize a pre dominantly electrochemical gradient of protons and no other ion? The answer to this question may lie in the environment in which the first living creatures evolved. Some of them may have been challenged by an acidic environment that lowered their internal pH (by a proton leak through their membranes) to lethal levels. To counteract these inci dents proton pumps evolved. Two independent systems were devel oped. One was a proton pump coupled to energetically downhill vectorial electron transport across membranes and the second was an ATP-dependent proton pump. Both of them pump protons outward from the cells generating an electrochemical gradient of protons.
Download or read book Regulation of Ca2 ATPases V ATPases and F ATPases written by Sajal Chakraborti and published by Springer. This book was released on 2015-12-10 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological membranes of cellular organization enfold an important group of membrane proteins called the ATPases, which are not only versatile in maintaining chemical gradient and electrical potential across the membrane but also bring metabolites necessary for cell metabolism and drive out toxins, waste products and solutes that otherwise can curb cell functions. ATPases are distributed virtually in all live forms starting from unicellular to multicellular and also in viruses. There are different types of ATPases, which differ in function and structure and in the type of ions they transport. The three main types of the ion pump ATPase family are: (i) P-type ATPases that transport different ions across membranes and Ca2+ATPases belongs to this catagory (ii) F-type ATPase in mitochondria, chloroplasts and bacterial plasma membranes produce ATP using the proton gradient; and (iii) V-type ATPase catalyzes ATP hydrolysis to transport solutes and maintains acidic pH in organelles like lysosomes. Genetic defects in either of the ATPases cause several diseases and a number of researches have demonstrated the involvement of the members of ATPases in the cell pathology and diseases, thereby penetrating exciting new areas of our understanding. In this book, the authors summarize recent knowledge about the molecular mechanisms associated with Ca2+-ATPase, V-ATPase and F-ATPase in intracellular and extracellular Ca2+ transport, mitochondrial ATP synthase, vesicular H+ transport, and lysosomal pH regulation. This book thereby bridges the gap between fundamental research and biomedical and pharmaceutical applications. The book provides an informative resource to improve ATPase research and modern therapeutic approaches toward different life threatening diseases that are associated with dysregulation of the ATPases.

Topics covered include: • Design considerations in biophysical-based lead screening • Thermodynamic characterization of protein-compound interactions • Characterizing targets and screening reagents with HDX-MS • Microscale thermophoresis methods (MST) • Screening with Weak Affinity Chromatography • Methods to assess compound residence time • 1D-NMR methods for hit identification • Protein-based NMR methods for SAR development • Industry case studies integrating multiple biophysical methods This text is ideal for academic investigators and industry scientists planning hit characterization campaigns or designing and optimizing screening strategies.
Download or read book Innovative Medicine written by Kazuwa Nakao and published by Springer. This book was released on 2015-10-13 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to innovative medicine, comprising the proceedings of the Uehara Memorial Foundation Symposium 2014. It remains extremely rare for the findings of basic research to be developed into clinical applications, and it takes a long time for the process to be achieved. The task of advancing the development of basic research into clinical reality lies with translational science, yet the field seems to struggle to find a way to move forward. To create innovative medical technology, many steps need to be taken: development and analysis of optimal animal models of human diseases, elucidation of genomic and epidemiological data, and establishment of “proof of concept”. There is also considerable demand for progress in drug research, new surgical procedures, and new clinical devices and equipment. While the original research target may be rare diseases, it is also important to apply those findings more broadly to common diseases. The book covers a wide range of topics and is organized into three complementary parts. The first part is basic research for innovative medicine, the second is translational research for innovative medicine, and the third is new technology for innovative medicine. This book helps to understand innovative medicine and to make progress in its realization.
Download or read book The Enzymes of Biological Membranes written by Anthony Martonosi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the information currently available on the transport systems of bacterial and animal cell membranes and their mode of coupling to metabolic supply of energy can be found in this volume. Consideration of the participating enzymes dictated the choice of topics: Several transport systems where little information is available on the enzymology of the process are not included, while separate chapters deal with y-glutamyl transpeptidase and intestinal disaccharidases which meet many of the requirements of transport enzymes. The volume also includes two chapters on photosynthetic membranes as a general introduction to the topic. Other aspects of biological transport and photosynthesis will be developed in detail in a forthcoming volume now in preparation. These chapters reveal the excitement and rapid advance of the field, the daily reports of new concepts, new techniques, and new experimental findings which instantly interact to generate further progress. Our aim was to provide a starting point for those who are just beginning, and an opportunity for others to stop, take stock, and start in a new direction. My warmest thanks to all who contributed to this volume.
