Download or read book Ribonucleotide Reductase written by Kristoffer Andersson and published by Nova Publishers. This book was released on 2008 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this book is the amazing enzyme ribonucleotide reductase (RNR), the enzyme responsible for the conversion of ribonucleotides to deoxyribonucleotides. The prerequisite for DNA-synthesis and DNA-repair in all living cells is the supply of the four deoxyribonucleotides. Such molecules result from the enzymatically difficult radical-induced reduction of ribonucleotides, a multistep chemical process catalyzed by RNR. RNR was the first enzyme in which the presence of an amino acid radical (a tyrosyl) in E. coli Class Ia RNR has been proven; since then several other biological amino acid radical species have been found on e.g. tryptophan, glycine, cysteine, lysine residues and on amino acid derived small cofactors like 2 tryptophanes in thryptophan-trypthanyl-radical or cysteine-tyrosyl-radical in other enzymes. As all known cellular life forms store their genetic information as DNA, RNR is likely to be found in all growing cells of every living organism, a fact that is confirmed by a rapidly increasing number of genomic screenings.

Download or read book Allosteric Enzymes written by Guy Herve and published by CRC Press. This book was released on 2020-11-26 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book compiles detailed information concerning a dozen of the best known allosteric enzymes, and so allows the comparison of their regulatory mechanisms and the confrontation of these mechanisms with the theoretical models. Stimulating and unexpected ideas emerge from these comparisons and emphasize the importance of developing various methods of investigation such as crystallography, X-ray solution scattering, and the study of fast movements in proteins and site-directed mutagenesis. This book is addressed to students and researchers interested in structure-function relationship in proteins, enzymology and metabolic regulation. It is also a basis for teaching.

Download or read book Allosteric Regulatory Enzymes written by Thomas W. Traut and published by Springer Science & Business Media. This book was released on 2007-09-11 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the most recent developments in the analysis of allosteric enzymes and provides a logical introduction to the limits for enzyme function as dictated by the factors that are limits for life. The book presents a complete description of all the mechanisms used for changing enzyme activity. It is extensively illustrated to clarify kinetic and regulatory properties. Eight enzymes are used as model systems after extensive study of their mechanisms. Wherever possible, the human form of the enzyme is used to illustrate the regulatory features.
Download or read book Amino Acids Peptides and Proteins written by R C Sheppard and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.
Download or read book Macromolecular Protein Complexes IV written by J. Robin Harris and published by Springer Nature. This book was released on 2022-09-23 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the latest findings of a wide variety of viral, prokaryotic and eukaryotic macromolecular protein complexes and builds upon the solid macromolecular foundations established by previous volumes of the Subcellular Biochemistry series. Thus, an almost encyclopaedic coverage of the broad field of protein complex structure and function has been established. The 17 interesting chapters included in this book have been organised into four sections: Soluble Protein Complexes, Membrane Protein Complexes, Fibrous Protein Complexes and Viral Protein Complexes. Significant topics present here are: Fatty Acid Synthase, the Fork Protection Complex, Ribonucleotide Reductase, the Kinetochore, G proteins, the FtsEX Complex, the Kainate Receptor, the Photosystem I-antenna, the Mycobacterial Arabinofuranosyltransferases, the the Bacterial Flagellum, the Actomyosin Complex, Motile Cilia, SLS Collagen Polymorphic Structures, and the Reovirus Capsid and Polymerase. Up-dates/expansion of chapter topics present in earlier volumes are now included in chapters here, e.g., those on Ferritin-like proteins and the Multi-tRNA Synthetase. The book is richly illustrated throughout, the result of an impressive integration of structural data from X-ray crystallography and cryo-electron microscopy. The functional aspects of protein-protein interactions are also given a high priority.
Download or read book Microbial Biochemistry written by G.N. Cohen and published by Springer Science & Business Media. This book was released on 2011-02-02 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial physiology, biochemistry, and genetics allowed the formulation of concepts that turned out to be important in the study of higher organisms. In the first section, the principles of bacterial growth are given, as well as the description of the different layers that enclose the bacterial cytoplasm, and their role in obtaining nutrients from the outside media through different permeability mechanism described in detail. A chapter is devoted to allostery and is indispensable for the comprehension of many regulatory mechanisms described throughout the book. Another section analyses the mechanisms by which cells obtain the energy necessary for their growth, glycolysis, the pentose phosphate pathway, the tricarboxylic and the anaplerotic cycles. Two chapters are devoted to classes of microorganisms rarely dealt with in textbooks, namely the Archaea, mainly the methanogenic bacteria, and the methylotrophs. Eight chapters describe the principles of the regulations at the transcriptional level, with the necessary knowledge of the machineries of transcription and translation. The next fifteen chapters deal with the biosynthesis of the cell building blocks, amino acids, purine and pyrimidine nucleotides and deoxynucleotides, water-soluble vitamins and coenzymes, isoprene and tetrapyrrole derivatives and vitamin B12. The two last chapters are devoted to the study of protein-DNA interactions and to the evolution of biosynthetic pathways. The considerable advances made in the last thirty years in the field by the introduction of gene cloning and sequencing and by the exponential development of physical methods such as X-ray crystallography or nuclear magnetic resonance have helped presenting metabolism under a multidisciplinary attractive angle. The level of readership presupposes some knowledge of chemistry and genetics at the undergraduate level. The target group is graduate students, researchers in academia and industry.
