Book Synopsis Copper Coordination with Protein, Peptides, and Small Molecules by : Whitnee Leigh Nettles
Download or read book Copper Coordination with Protein, Peptides, and Small Molecules written by Whitnee Leigh Nettles and published by . This book was released on 2016 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Copper is an essential element for all living organisms. However, due to its low redox potential it can be involved in the production of reactive oxygen species; where excess amounts of copper can be exceptionally toxic. In humans, malfunctions in copper metabolism are linked to diseases such as Menkes syndrome, Wilson’s disease, prion disease, and Alzheimer’s disease. Maintenance of copper homeostasis requires a number of proteins, such as copper transporters and chaperones to deliver copper to the correct protein while limiting free copper in the cell. Therefore, understanding the thermodynamics of copper(II) coordination in proteins is critical to our understanding of copper homeostasis. Herein we report human carbonic anhydrase II contains a novel copper binding site with picomolar affinity. A full characterization of the structure and thermodynamics associated with the coordination of both Cu atoms into their respective sites is discussed. Techniques including paramagnetic nuclear magnetic resonance spectroscopy (NMR), and x-ray absorption spectroscopy (XAS) techniques provide insight into the high affinity CuA̳ coordination environment. A detailed characterization of this high affinity binding site and related peptide-bound model complexes are included, with the results providing insights into the chemistry and physiological impact of copper binding in human carbonic anhydrase II.

Available in PDF, EPUB and Kindle. Book excerpt: A wide range of researchers are currently investigating different properties and applications for copper-containing proteins. Biochemists researching metal metabolism in organisms ranging from bacteria to plants to animals are working in a completely different area of discovery than scientists studying the transportation and regulation of minerals and small molecule nutrients. They are both working with copper-containing proteins, but in very different ways and with differing anticipated outcomes.
Download or read book The Prion Protein written by Jorg Tatzelt and published by . This book was released on 2010 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: A conformational transition of the cellular prion protein (PrPC) into an aberrantly folded isoform designated scrapie prion protein (PrPSc) is the hallmark of a variety of neurodegenerative disorders collectively called prion diseases. They include Creutzfeldt-Jakob disease and Gerstmann-Stäussler-Scheinker syndrome in humans, scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle and chronic wasting disease (CWD) in free-ranging deer. In contrast to the deadly properties of misfolded PrP, PrPC seems to possess a neuroprotective activity. More-over, animal models indicated that the stress-protective activity of PrPC and the neurotoxic effects of PrPSc are somehow interconnected. In this timely book, leading scientists in the field have come together to highlight the apparently incongruous activities of different PrP conformers. The articles outline current research on celluar pathways implicated in the formation and signaling of neurotoxic and physiological PrP isoforms and delineate future research direction. Topics covered include the physiologcial activity of PrPC and its possible role as a neurotrophic factor, the finding that aberrant PrP conformers can cause neurodegeneration in the absence of infectious prion propagation, the requirement of the GPI anchor of PrPC for the neurotoxic effects of scrapie prions, the pathways implicated in the formation and neurotoxic properties of cytosolically localized PrP, the impact of metal ions on the processing of PrP, and the role of autophagy in the propagation and clearance of PrPSc. The book is fully illustrated and chapters include comprehensive reference sections. Essential reading for scientists involved in prion research.

Book Synopsis Small Molecule DNA and RNA Binders by : Martine Demeunynck
Download or read book Small Molecule DNA and RNA Binders written by Martine Demeunynck and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 754 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of molecules that selectively bind to nucleic acids has provided many details about DNA and RNA recognition. The range of such substances, such as metal complexes, peptides, oligonucleotides and a wide array of synthetic organic compounds, is as manifold as the functions of nucleic acids. Nucleic acid recognition sequences are often found in the major or minor groove of a double strand, while other typical interactions include intercalation between base pairs or the formation of triple or quadruple helices. One example of a binding mode that has recently been proposed is end stacking on such complex structures as the telomere tetraplex. In this comprehensive book, internationally recognized experts describe in detail the important aspects of nucleic acid binding, and in so doing present impressive approaches to drug design. Since typical substances may be created naturally or synthetically, emphasis is placed on natural products, chemical synthesis, the use of combinatorial libraries, and structural characterization. The whole is rounded off by contributions on molecular modeling, as well as investigations into the way in which any given drug interacts with its nucleic acid recognition site.

The second part discusses numerous carefully selected examples, chosen to illustrate the wide range of applicability of molecular modeling to metal complexes and the approaches being taken to dealing with some of the difficulties involved. While the general outline is similar to that of the first edition, many of the examples chosen for discussion reflect the changes of the past five years. In the third part, the reader learns how to apply Molecular Modeling to a new system and how to interpret the results. The accompanying software features 20 tutorial lessons based on examples from the literature and the book itself.

Book Synopsis Theoretical Biochemistry by : Leif A. Eriksson
Download or read book Theoretical Biochemistry written by Leif A. Eriksson and published by Elsevier. This book was released on 2001-02-19 with total page 719 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical chemistry has been an area of tremendous expansion and development over the past decade; from an approach where we were able to treat only a few atoms quantum mechanically or make fairly crude molecular dynamics simulations, into a discipline with an accuracy and predictive power that has rendered it an essential complementary tool to experiment in basically all areas of science. This volume gives a flavour of the types of problems in biochemistry that theoretical calculations can solve at present, and illustrates the tremendous predictive power these approaches possess.A wide range of computational approaches, from classical MD and Monte Carlo methods, via semi-empirical and DFT approaches on isolated model systems, to Car-Parinello QM-MD and novel hybrid QM/MM studies are covered. The systems investigated also cover a broad range; from membrane-bound proteins to various types of enzymatic reactions as well as inhibitor studies, cofactor properties, solvent effects, transcription and radiation damage to DNA.
Book Synopsis Metal Sites in Proteins and Models by : H.A.O. Hill
Download or read book Metal Sites in Proteins and Models written by H.A.O. Hill and published by Springer Science & Business Media. This book was released on 1999-04-01 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological chemistry is a major frontier of inorganic chemistry. Three special volumes devoted to Metal Sites in Proteins and Models address the questions: how unusual ("entatic") are metal sites in metalloproteins and metalloenzymes compared to those in small coordination complexes? and if they are special, how do polypeptide chains and co-factors control this? The chapters deal with iron, with metal centres acting as Lewis acids, metals in phosphate enzymes, with vanadium, and with the wide variety of transition metal ions which act as redox centres. They illustrate in particular how the combined armoury of genetics and structure determination at the molecular level are providing unprecedented new tools for molecular engineering.
