Book Description
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

Book Description
Chemistry and Methods of Enzymes, Third Edition focuses on the processes, methodologies, and reactions in enzyme chemistry, as well as kinetics, nucleases, esterases, and carbohydrates. The publication first underscores the general properties of enzymes, including chemical nature, occurrence, numerical characterization of enzyme concentration, kinetics of enzyme reactions, preparation of commercial enzymes, purification and preservation of enzymes, relations of vitamins to enzymes, and zymogens and kinases. The text then takes a look at esterases and carbohydrates. Topics include pectin depolymerase, heparinase, xylanase, chitinase, dextranase, trehalase, nucleotide phosphatases, glucosulfatase, and gastric lipase. The manuscript examines nucleases, nuclein deaminases, amidases, proteolytic enzymes, and hydrases. Discussions focus on enolase, aconitase, peptidases as metalloproteins, glutaminases, aspartase, urease, adenosine deaminase, and nucleoside phosphorylase. The book also elaborates on iron and copper enzymes, dehydrogenases containing coenzymes I and II, and yellow enzymes. The text is a dependable source of data for chemists and researchers wanting to dig deeper into the chemistry and methods of enzymes.

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.

Book Description
The outlook of organic synthesis has changed many times during its tractable history. The initial focus on the synthesis of substances typical of living matter, exemplified by the first examples of organic chemistry through the synthesis of urea from inorganic substances by Liebig, was accepted as the birth of organic chemistry, and thus also of organic synthesis. Although the early developments in organic synthesis closely followed the pursuit of molecules typical in nature, towards the end of the 19th century, societal pressures placed higher demands on chemical methods appropriate for the emerging age of industrialization. This led to vast amounts of information being generated through the discovery of synthetic reactions, spectroscopic techniques and reaction mechanisms. The basic organic functional group transformations were discovered and improved during the early part of this century. Reaction mechanisms were elucidated at a growing pace, and extremely powerful spectroscopic tools, such as infrared, nuclear magnetic resonance and mass spectrometry were introduced as everyday tools for a practising organic chemist. By the 1950s, many practitioners were ready to agree that almost every molecule could be syn thesized. Some difficult stereochemical problems were exceptions; for example Woodward concluded that erythromycin was a "hopelessly complex target". This frustration led to a hectic phase of development of new and increasingly more ingenious protecting group strategies and functional group transformations, and also saw the emergence of asymmetric synthesis.

Book Description
This text covers the field of steady-state kinetics from basic principles to the control of the multi-enzyme systems which constitute metabolic pathways. Emphasis is placed on the interpretation of the kinetic behaviour of enzyme-catalyzed reactions in terms of mechanisms. Algorithms are developed which can be implemented in computer programs for the derivation of equations. The treatment of steady-state enzyme kinetics is extended to allosteric enzymes and subunit interactions in polymeric enzymes. Principles are presented which provide for mathematical analysis of the control of multi-enzyme systems. Problems are included at the end of each chapter and their solutions are found at the end of the book. This book will be a useful text for advanced undergraduates and graduate students taking courses in enzyme chemistry and enzyme kinetics.

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.

Book Description
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.
