Enzymatic Reaction Mechanisms

Pages : 848 pages

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 Walshs book is both out-of-date and out-of-focus in todays world of enzymatic mechanisms.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.

High Resolution EPR
Author : Graeme Hanson,Lawrence Berliner
Publisher : Springer Science & Business Media
Release Date : 2009-06-19
ISBN 10 : 0387848568
Pages : 666 pages

Metalloproteins comprise approximately 30% of all known proteins, and are involved in a variety of biologically important processes, including oxygen transport, biosynthesis, electron transfer, biodegradation, drug metabolism, proteolysis, and hydrolysis of amides and esters, environmental sulfur and nitrogen cycles, and disease mechanisms. EPR spectroscopy has an important role in not only the geometric structural characterization of the redox cofactors in metalloproteins but also their electronic structure, as this is crucial for their reactivity. The advent of x-ray crystallographic snapshots of the active site redox cofactors in metalloenzymes in conjunction with high-resolution EPR spectroscopy has provided detailed structural insights into their catalytic mechanisms. This volume was conceived in 2005 at the Rocky Mountain Conference on Analytical Chemistry (EPR Symposium) to highlight the importance of high-resolution EPR spectroscopy to the structural (geometric and electronic) characterization of redox active cofactors in metalloproteins. We have been fortunate to have enlisted internationally recognized experts in this joint venture to provide the scientific community with an overview of high-resolution EPR and its application to metals in biology. This volume, High-Resolution EPR: Applications to Metalloenzymes and Metals in Medicine, covers high-resolution EPR methods, iron proteins, nickel and copper enzymes, and metals in medicine. An eloquent synopsis of each chapter is provided by John Pilbrow in the Introduction. A second volume, Metals in Biology: Applications of High-Resolution EPR to Metalloenzymes, will appear later this year covering the complement of other metalloproteins. One of the pioneers in the development of pulsed EPR and its application to metalloproteins was Arthur Schweiger, whose contribution we include in this volume. Unfortunately, he passed away suddenly during the preparation of this volume. The editors and coauthors are extremely honored to dedicate this volume to the memory of Arthur Schweiger in recognition of his technical advances and insights into pulsed EPR and its application to metalloproteins. Arthur was extremely humble and treated everyone with equal respect. He was a gifted educator with an ability to explain complex phenomena in terms of simple intuitive pictures, had a delightful personality, and continues to be sadly missed by the community. It is an honor for the editors to facilitate the dissemination of these excellent contributions to the scientific community. Suggestions for future volumes are always appreciated.

Chirality in Biological Nanospaces
Author : Nilashis Nandi
Publisher : CRC Press
Release Date : 2011-07-27
ISBN 10 : 1439840024
Pages : 209 pages

Chirality is widely studied and omnipresent in biological molecules. However, how the retention of enantiomeric forms persists in many life processes without racemization is still unclear, and the molecular understanding of the stringent chiral specificity in enzymatic reactions is sparse. An overview of the influence of chirality in driving reactions within enzymatic cavities, Chirality in Biological Nanospaces: Reactions in Active Sites covers: Influences of molecular chirality on the structure of the active site and network of interactions to drive reactions with improved speed, accuracy, and efficiency The conserved features of the organization of the active site structures of enzymes The intricate interplay of electrostatic, hydrophobic, and van der Waals interactions Interactions between the active site residues and the substrate molecules Despite being time-consuming and expensive, trial-and-error is often the primary method used to develop synthetic enzymes. This book describes methods that combine crystallographic studies with electronic structure-based computational analysis. These methods may lead to future elucidation of new drugs that can target biological active sites with better efficacy and can be used to design custom-made novel biocytes with improved efficiency.

Introduction to Enzyme and Coenzyme Chemistry

ISBN 10 : 1118348990
Pages : 280 pages

Enzymes are giant macromolecules which catalyse biochemical reactions. They are remarkable in many ways. Their three-dimensional structures are highly complex, yet they are formed by spontaneous folding of a linear polypeptide chain. Their catalytic properties are far more impressive than synthetic catalysts which operate under more extreme conditions. Each enzyme catalyses a single chemical reaction on a particular chemical substrate with very high enantioselectivity and enantiospecificity at rates which approach “catalytic perfection”. Living cells are capable of carrying out a huge repertoire of enzyme-catalysed chemical reactions, some of which have little or no precedent in organic chemistry. The popular textbook Introduction to Enzyme and Coenzyme Chemistry has been thoroughly updated to include information on the most recent advances in our understanding of enzyme action, with additional recent examples from the literature used to illustrate key points. A major new feature is the inclusion of two-colour figures, and the addition of over 40 new figures of the active sites of enzymes discussed in the text, in order to illustrate the interplay between enzyme structure and function. This new edition provides a concise but comprehensive account from the perspective of organic chemistry, what enzymes are, how they work, and how they catalyse many of the major classes of enzymatic reactions, and will continue to prove invaluable to both undergraduate and postgraduate students of organic, bio-organic and medicinal chemistry, chemical biology, biochemistry and biotechnology.
