This book was released on 2003 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzyme catalysis is an important and vigorously developing field of basic and applied research, posing challenging problems to biochemists and chemists. This volume embraces modern areas of enzyme catalysis where other books in the field concentrate mainly on kinetic, bioorganic and biochemical aspects of the enzyme catalysis and do not cover biophysical and physicochemical problems. Topics covered include: modern physical and kinetic methods of investigation;contemporary theories of elementary chemical processes in enzymes; structure, dynamics and action mechanism of enzyme active sites; concept of pretransition state; theory of long-range electron transfer and proton translocation;mechanisms of tough biochemical reactions (dinitrogen reduction, light energy conversation, water photooxidation, hydroxilation);the achievements and problems of biomimetic chemical reactions.

This book was released on 2012-12-06 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymes perform the executive role in growth, energy conversion, and repair of a living organism. Their activity is adjusted to their en vironment within the cell, being turned off, switched on, or finely tuned by specific metabolites according to demands at the physiologi cal level. Each enzyme discovered in the long history of enzymology has revealed its own individuality. Even closely related members of a family differ in specificity, stability or regulatory properties. Despite these, at first sight overwhelming aspects of individuality, common factors of enzymic reactions have been recognized. Enzymes are stereospecific catalysts even when a nonspecific process would yield the same product. Knowledge of the detailed stereochemistry of an enzymic reaction helps to deduce reaction mechanisms and to ob tain insight into the specific binding of substrates at the active site. This binding close to catalytically competent groups is related to the enormous speed of enzyme-catalyzed reactions. The physical ba sis of rate-enhancement is understood in principle and further exploit ed in the design of small organic receptor molecules as model enzymes. These aspects of enzyme catalysis are discussed in Session 1. Session 2 emphasizes the dynamic aspects of enzyme substrate inter action. Substrate must diffuse from solution space to the enzyme's surface. This process is influenced and can be greatly facilitated by certain electrostatic propterties of enzymes. The dynamic events during catalysis are studied by relaxation kinetics or NMR techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Far more than a comprehensive treatise on initial-rate and fast-reaction kinetics, this one-of-a-kind desk reference places enzyme science in the fuller context of the organic, inorganic, and physical chemical processes occurring within enzyme active sites. Drawing on 2600 references, Enzyme Kinetics: Catalysis & Control develops all the kinetic tools needed to define enzyme catalysis, spanning the entire spectrum (from the basics of chemical kinetics and practical advice on rate measurement, to the very latest work on single-molecule kinetics and mechanoenzyme force generation), while also focusing on the persuasive power of kinetic isotope effects, the design of high-potency drugs, and the behavior of regulatory enzymes. Historical analysis of kinetic principles including advanced enzyme science Provides both theoretical and practical measurements tools Coverage of single molecular kinetics Examination of force generation mechanisms Discussion of organic and inorganic enzyme reactions
Download or read book Enzyme Catalysis and Regulation written by Gorden Hammes and published by Elsevier. This book was released on 2012-12-02 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzyme Catalysis and Regulation is an introduction to enzyme catalysis and regulation and covers topics ranging from protein structure and dynamics to steady-state enzyme kinetics, multienzyme complexes, and membrane-bound enzymes. Case studies of selected enzyme mechanisms are also presented. This book consists of 11 chapters and begins with a brief overview of enzyme structure, followed by a discussion on methods of probing enzyme structure such as X-ray crystallography and optical spectroscopy. Kinetic methods are then described, with emphasis on the general principles of steady-state and transient kinetics. The chemical principles involved in enzyme catalysis are also discussed, and case studies of a few well-documented enzymes are presented. The regulation of enzyme activity is analyzed from a nongenetic viewpoint, with particular reference to binding isotherms and models for allosterism. Two particular enzymes, aspartate transcarbamoylase and phosphofructokinase, are used as examples of well-studied regulatory enzymes. The last two chapters focus on multienzyme complexes and membrane-bound enzymes. This monograph is intended for graduate students, advanced undergraduates, and research workers in molecular biology and biochemistry.

Download or read book ENZYMES Catalysis Kinetics and Mechanisms written by N.S. Punekar and published by Springer. This book was released on 2018-11-11 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This enzymology textbook for graduate and advanced undergraduate students covers the syllabi of most universities where this subject is regularly taught. It focuses on the synchrony between the two broad mechanistic facets of enzymology: the chemical and the kinetic, and also highlights the synergy between enzyme structure and mechanism. Designed for self-study, it explains how to plan enzyme experiments and subsequently analyze the data collected. The book is divided into five major sections: 1] Introduction to enzymes, 2] Practical aspects, 3] Kinetic Mechanisms, 4] Chemical Mechanisms, and 5] Enzymology Frontiers. Individual concepts are treated as stand-alone chapters; readers can explore any single concept with minimal cross-referencing to the rest of the book. Further, complex approaches requiring specialized techniques and involved experimentation (beyond the reach of an average laboratory) are covered in theory with suitable references to guide readers. The book provides students, researchers and academics in the broad area of biology with a sound theoretical and practical knowledge of enzymes. It also caters to those who do not have a practicing enzymologist to teach them the subject.

Available in PDF, EPUB and Kindle. Book excerpt: MOLECULAR ENZYMOLOGY, BECAUSE OF ITS CHEMICAL AND MATHEMATICAL content, is often regarded as a formidable and forbidding topic by undergraduates on a biology or biochemistry course, As a result of teaching enzymology to undergraduates for a number of years, we recognize the areas which appear to cause the most common difficulties in conceptual understanding. We feel that a book treating those areas by means of a logical approach carefully developed from basic principles fills a gap in the multiplicity of enzymology texts currently available. In writing this book we h;:lVe had in mind the needs of Honours Biochemistry students, in particular those who may take a special interest in enzymology. The text covers the main bulk of the material required in the second and third years of such courses. In addition, those taking courses in Biological Chemistry may well find the book to be of central interest. The book begins with a description of the fundamentals of catalysis, illustrating these with simple chemical reactions which may be supposed to serve as models of catalytic processes. Protein structure is discussed in terms of the fundamental forces which determine the shape and dynamic behaviour of protein molecules. The approach emphasizes those features thought to be most intimately involved in the catalytic function of enzyme molecules, and is illustrated with specific examples.
Download or read book The Enzyme Catalysis Process written by A. Cooper and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents the proceedings of a NATO Advanced Studies Instituteheld near Barga (Italy), July 11-23, 1988, involving over 90 participants from more than twelve countries of Europe, North America and elsewhere. It was not our intention at this meeting to present a complete up-to-the-minute review of current research in enzyme catalysis but t·ather, in accord wi th the intended spiri t of NATO ASis, to gi ve an opportunity for advanced students and researchers in a wide variety of disciplines to meet tagether and study the problern from different points of view. Hence the lectures cover topics rauging from the purely theoretical aspects of chemical reaction kinetics in condensed matter through practical experimental approaches to enzyme structure, dynamics and mechanism, including the new experimental opportunities arising from genetic engineering techniques. Our approachwas unashamedly physical, both because the more biochemical aspects of enzymology are amply covered elsewhere and because progress in our understanding and application of the molecular basis of enzymic processes must ultimately come from advances in physical knowledge. We tried to cover as wide a spectrum as possible, and succeeded in gathering an expert and enthusiastic team of speakers, but there . are some inevitable omissions. In particular, and with hindsight, our discussions might have been enriched by more detailed coverage of general aspects of chemical catalysis - but readers requiring this background should find adequate references herein.
Download or read book Molecular and Cellular Enzymology written by Jeannine Yon-Kahn and published by Springer Science & Business Media. This book was released on 2011-07-23 with total page 809 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular and Cellular Enzymology addresses not only experienced enzymologists but also students, teachers and academic and industrial researchers who are confronted with enzymological problems during their fundamental or applied research. In this field there is an urgent need for training in order to meet the requirements of both research and industrial endeavours. This book consists of several levels. Practical aspects and elementary explanations are given for the benefit of non-specialists’ and students’ understanding. In order to facilitate the task of students, two typographies have been adopted. The main text corresponds to basic knowledge, whereas text in a smaller font provides more specialised information. Specialists will also find topics more deeply expounded with the principal bibliographic references cited. The bibliography, however, is not exhaustive; the choice includes general books and review articles as well as some specialised articles. In this book, for the first time, the different molecular and cellular aspects of enzymology are presented together. Until now, there has been no book available in which these different aspects are treated in the same volume. In addition, besides the theoretical developments, this book provides a wealth of practical information for experimentalists.
