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.

Available in PDF, EPUB and Kindle. Book excerpt: Bioinorganic Chemistry of Copper focuses on the vital role of copper ions in biology, especially as an essential metalloenzyme cofactor. The book is highly interdisciplinary in its approach--the outstanding list of contributors includes coordination chemists, biochemists, biophysicists, and molecular biologists. Chapters are grouped into major areas of research interest in inorganic copper chemistry, spectroscopy, oxygen chemistry, biochemistry, and molecular biology. The book also discusses basic research of great potential importance to pharmaceutical scientists. This book is based on the first Johns Hopkins University Copper Symposium, held in August 1992. Researchers in chemistry, biochemistry, molecular biology, and medicinal chemistry will find it to be an essential reference on its subject.

Available in PDF, EPUB and Kindle. Book excerpt: Cofactors extend the chemistry of life. Redox reactions in photosynthesis, nitrogen fixation, and other metabolic pathways depend on metal cofactors. Copper is an essential element in biology, participating in redox reactions and biological catalysis. Copper proteins are classified by their copper centers as type-1, type-2, type-3, CuA, CuB, or Cuz. Type-1 proteins, such as azurin or plastocyanin, are primarily involved in electron transport. Type-1 centers are the most studied copper site at the spectroscopic and structural level. In the type-1 center, the copper cofactor is coordinated by a cysteine, two histidines, and generally a weak axial methionine. This coordination geometry gives rise to several ligand-to-metal charge-transfer transitions, producing a characteristic blue or green type-1 spectrum. In "blue" type-1 copper proteins, the cysteine-copper bond is exceptionally small (2.1 Å) and the methionine-copper bond is abnormally long (2.9 Å). In green type-1 copper proteins, the cysteine-copper bond elongates and the methionine-copper bond contracts. The redox range varies from +83 mV to over +1000 mV. Protein tuning modulates the large variations observed in the redox range and spectral properties. The mechanism of protein tuning is poorly understood. In chapter 2, I characterize a family of four blue copper proteins called auracyanins. The auracyanins, named A-D, were found to have a redox range from +83 mV to +423 mV, and range in color from blue to green. In chapter 3, I take advantage of the tuning variations within the auracyanin family to map the spectral changes to the protein-protein interaction domain. The protein-protein interaction domain has never previously been implicated in protein tuning. These results likely explain how seemingly energetically uphill electron transfer reactions commonly occur with copper proteins. In chapter 4, I perform mutagenesis on the weak axial ligand in auracyanin D. Auracyanin D is a green copper protein, and has the lowest redox potential ever measured for a copper protein. Significant work has been done on axial ligands in blue type-1 copper proteins, but never in green type-1 copper proteins. I found that substitutions to the axial ligand in green copper sites are much larger than their blue copper protein counterparts. In chapter 5, I conclude with a computational approach showing significant variation in the coordinating ligands of uncharacterized copper proteins. I believe examination of these proteins by a reverse biochemical approach will add more clarity to the role of protein tuning and expand the limits of copper tuning.
Download or read book Multi copper Oxidases written by Albrecht Messerschmidt and published by World Scientific. This book was released on 1997 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological activation of dioxygen is a key reaction in biological systems. Enzymes involved in direct oxygen activation are oxidases and oxygenases. Multi-copper oxidases are an important class of oxidases reducing dioxygen in a four-electron reduction to water with concomitant one-electron oxidation of the reducing substrate. The progress in the characterization and understanding of the structure and function of these enzymes has advanced so tremendously over the last ten years that the publication of a book documenting these achievements has been overdue.Especially the recent discovery of a key role of the FET3 protein of Saccharomyces cerevisae, a multi-copper oxidase, in iron metabolism of this eukaryote has underpinned the function of the plasma multi-copper oxidase ceruloplasmin in vetebrate iron transport. The lately determined x-ray structure of human ceruloplasmin confirms its close structural relatedness to the plant multi-copper oxidases ascorbate oxidase and laccase and due to strong amino-acid sequence similarities has allowed to construct a useful model of the more distantly related blood-clotting factor VIII.This book contains review articles from experts in the field, dealing with modern spectroscopy, enzyme kinetics, bioinorganic chemistry, x-ray crystallography, electron transfer reactions, molecular biology, medical aspects and potential industrial applications of the three main members of multi-copper oxidases, i.e., laccase, ascorbate oxidase and ceruloplasmin.
