ENZYMES: Catalysis, Kinetics and Mechanisms


Book Description

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.




Enzyme Catalysis and Regulation


Book Description

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.




Enzyme Kinetics: Catalysis and Control

A Study of Enzymes


Book Description

First published in 1990, this comprehensive monograph consists of two parts: Volume I, entitled Enzyme Catalysis, Kinetics, and Substrate Binding; and Volume II, entitled Mechanism of Enzyme Action. Volume I focuses on several aspects of enzyme catalytic behavior, their steady-state and transient-state kinetics, and the thermodynamic properties of substrate binding. Packed with figures, tables, schemes, and photographs, this volume contains over 1,000 references, including references regarding enzymology's fascinating history. This comprehensive book is of particular interest to enzymology students, teachers, and researchers. Volume II presents selected "cutting edge" examples of techniques and approaches being pursued in biochemistry. This up-to-date resource includes 11 chapters, which illustrate important theoretical and practical aspects of enzyme mechanisms. It also features selected examples in which today's most important techniques, ideas, and theories are used to elaborate on the intricate nature of enzyme action mechanisms. This particular volume provides important information for both the novice and the seasoned investigator.




Enzymatic Reaction Mechanisms


Book Description

Books dealing with the mechanisms of enzymatic reactions were written a generation ago. They included volumes entitled Bioorganic Mechanisms, I and II by T.C. Bruice and S.J. Benkovic, published in 1965, the volume entitled Catalysis in Chemistry and Enzymology by W.P. Jencks in 1969, and the volume entitled Enzymatic Reaction Mechanisms by C.T. Walsh in 1979. The Walsh book was based on the course taught by W.P. Jencks and R.H. Abeles at Brandeis University in the 1960's and 1970's. By the late 1970's, much more could be included about the structures of enzymes and the kinetics and mechanisms of enzymatic reactions themselves, and less emphasis was placed on chemical models. Walshs book was widely used in courses on enzymatic mechanisms for many years. Much has happened in the field of mechanistic enzymology in the past 15 to 20 years. Walshs book is both out-of-date and out-of-focus in todays world of enzymatic mechanisms. There is no longer a single volume or a small collection of volumes to which students can be directed to obtain a clear understanding of the state of knowledge regarding the chemicals mechanisms by which enzymes catalyze biological reactions. There is no single volume to which medicinal chemists and biotechnologists can refer on the subject of enzymatic mechanisms. Practitioners in the field have recognized a need for a new book on enzymatic mechanisms for more than ten years, and several, including Walsh, have considered undertaking to modernize Walshs book. However, these good intentions have been abandoned for one reason or another. The great size of the knowledge base in mechanistic enzymology has been a deterrent. It seems too large a subject for a single author, and it is difficult for several authors to coordinate their work to mutual satisfaction. This text by Perry A. Frey and Adrian D. Hegeman accomplishes this feat, producing the long-awaited replacement for Walshs classic text.




Mechanisms of Catalysis


Book Description

The remarkable expansion of information leading to a deeper understanding of enzymes on the molecular level necessitated the development of this volume which not only introduces new topics to The Enzymes series but presents new information on some covered in Volume I and II of this edition.

Comprehensive Enzyme Kinetics


Book Description

Welcome to your study of enzyme kinetics, the subject that underlies all enzymology, which in turn underlies all aspects of biochemistry. This text will give you an introduction to a wide range of topics that constitute the modern enzyme kinetics. This textbook is directed at graduate students in biochemistry, chemistry, and life sciences, for advanced courses in enzyme kinetics, enzymology, and enzyme chemistry. For this reason, the whole book is organized in a systematic and scholarly fashion. It is unlikely that the student will be expected to cover everything in the text, but in a later career she or he may find it an invaluable reference for topics that are needed in practice. The concepts, definitions and detailed algebra of enzyme kinetics are laid out in accurate detail. For that reason, this textbook can also serve as a handbook for enzyme kinetics for research workers in the field. The research worker will find it a useful source, which can be used for solving the daily experimental problems in the laboratory. The preparation of the manuscript for this book was under the constant surveillance of W. Wallace Cleland, Professor of Chemical Science at the University of Wisconsin in Madison, and one of the founders of modern enzyme kinetics. Without his help and advice, this bookwould not be possible. Several versions of the manuscript were constantly corrected and improved by Svetlana Professor of Biochemistry at the University of Novi Sad.
