Download or read book Mn Manganese written by and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume, "Manganese" D 5, continues the description of the manganese complexes. The arrangement of the complexes in these D volumes is based on the ligand type. The introduction, on p. 1, shows the classes of complexes, which have already been described in Chapters 1 to 21 in the Volumes D 1 (1979), D 2 (1980), D 3 (1982), and D 4 (1985). In Chapters 22 to 29 of this volume are treated complexes with amine-N-polycarboxylic acids, hydrazinecarboxylic acids, amides, hydrazides, derivatives of hydroxylamine (e.g., hydroxamic acids), oximes and nitroso compounds, azo compounds, and triazenes. A survey at the beginning of each of these sections gives information on the most characteristic features of the various complex types. Because of the complexometric relevance of the complexes with amine-N-polycarboxylic acids, there are many studies concerning the existence and the stability of the complexes in solution. Numerous X-ray investigations, reported for the complexes with urea or with amides and hydrazides of carboxylic acids, show the different structures of the compounds as a result of the varying bonding sites of the ligands. Complexes with hydrazides (e.g., with isonicotino hydrazide) are of special interest, due to their biological activity. Complexes with hydroxamic acids, oximes or azo compounds have been studied mostly in aqueous organic or pure organic solvents. The characteristic intense colors of many solutions are used for the analytical determination of manganese.

This book was released on 2019-11-05 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactions catalyzed by metalloenzymes have great potential for applications in the biotechnology and pharmaceutical industries. While only a few of these enzymes have yet been used in such applications, in the last few decades numerous efficient, selective, environmentally friendly and economical synthetic analogues have been described, including supramolecular, polymeric, nanoparticulate and lowmolecular- weight organometallic complexes, and metal organic frameworks. In this Research Topic, we present a collection of original research and review articles that show significant recent advances made in the rational design of such artificial metalloenzymes.
Download or read book Sustaining Life on Planet Earth Metalloenzymes Mastering Dioxygen and Other Chewy Gases written by Peter M. H Kroneck and published by Springer. This book was released on 2015-02-23 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: MILS-15 provides an up-to-date review of the metalloenzymes involved in the activation, production, and conversion of molecular oxygen as well as the functionalization of the chemically inert gases methane and ammonia. Found either in aerobes (humans, animals, plants, microorganisms) or in anaerobes (so-called “impossible bacteria”) these enzymes employ preferentially iron and copper at their active sites, in order to conserve energy by redox-driven proton pumps, to convert methane to methanol, or ammonia to hydroxylamine or other compounds. When it comes to the light-driven production of molecular oxygen, the tetranuclear manganese cluster of photosystem II must be regarded as the key player. However, dioxygen can also be produced in the dark, by heme iron-dependent dismutation of oxyanions. Metalloenzymes Mastering Dioxygen and Other Chewy Gases is a vibrant research area based mainly on structural and microbial biology, inorganic biological chemistry, and environmental biochemistry. All this is covered in an authoritative manner in 7 stimulating chapters, written by 21 internationally recognized experts, and supported by nearly 1100 references, informative tables, and over 140 illustrations (many in color). MILS-15 provides excellent information for teaching; it is also closely related to MILS-14, The Metal-Driven Biogeochemistry of Gaseous Compounds in the Environment. Peter M. H. Kroneck is a bioinorganic chemist who is exploring the role of transition metals in biology, with a focus on functional and structural aspects of microbial iron, copper, and molybdenum enzymes and their impact on the biogeochemical cyles of nitrogen and sulfur. Martha E. Sosa Torres is an inorganic chemist, with special interests in magnetic properties of newly synthesized transition metal complexes and their reactivity towards molecular oxygen, applying kinetic, electrochemical, and spectroscopic techniques.
Download or read book Bioinorganic Chemistry written by D.P. Kessissoglou and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioinorganic chemistry is primarily concerned with the role of metal atoms in biology and is a very active research field. However, even though such important structures of metalloenzymes are known, as the MoFeCo of nitrogenase, Cu or Mn superoxide dismutase and plastocyanin, the synthetic routes to the modelling of such centers remains a matter of acute scientific interest. Other metalloenzymes, such as the Mn center of the oxygen evolving complex of PSII, are still the focus of in-depth examination, both spectroscopic and structural. Another area of concern is the interaction between drugs and metals and metal ion antagonism. Understanding the chemistry of metal ions in biological systems will bring benefits in terms of understanding such problems as biomineralization and the production of advanced materials by micro-organisms. The 29 contributions to Bioinorganic Chemistry: An Inorganic Perspective of Life give an excellent summary of the state of the art in this field, covering areas from the NMR of paramagnetic molecules to the use of lanthanide porphyrins in artificial batteries.

Download or read book Modeling the Active Sites of Metalloenzymes with Thiolate Coordination written by Curtis Eugene Moore and published by . This book was released on 2007 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrile Hydratase (NHase) is a bacterial enzyme which catalyzes the hydrolysis of organic nitriles to their corresponding amides. The active site of NHase contains Fe (III) or Co(III) ions in an unusual coordination sphere containing 2 amide N atoms and three S donors. The research described herein is an attempt to model this active site using two different model systems: one that generates metal-coordinated imines, and one that generates metal-coordinated amides. Using 2,20́9-dithiodibenzaldehyde and derivatives of 2,20́9-dithiodisalicylic acid as reactants, several new and interesting metal coordinated imine and metal coordinated amide complexes have been synthesized. The synthesis and crystallization of several new organic and ligand species is discussed as well. The synthesis of a Co complex that resembles the active site of NHase is reported herein, along with several other new organometallic species. Also, two projects using computational chemistry are reported: one modeling trispyrazolylborate (Tp) complexes of iron and copper, and one modeling iron, manganese, and copper complexes of pentadentate imine/phenolate ligands. Complexes of Tp ligands with relatively bulky substituents in the 3-position are subject to isomerization through a borotropic shift. Computational chemistry has shed light on the energetics behind the borotropic shift. Calculations on the CO stretching frequency of several different TpCu(I)CO complexes have been carried out in an effort to match experimental data and generate predictive values for several other species not yet synthesized. This stretching frequency can generally be directly related to the electron withdrawing/donating character of the Tp ligand attached to the metal center. Pentdentate imine/phenolate ligands can coordinate to transition metals in a number of isomers. Computational chemistry has been used to shed light on the structural preferences of the iron, manganese, and copper species. These calculations were able to match the experimental data for crystallographically characterized species, and the metal complexes were shown to have specific structural preferences depending on the identity of the metal used.
