LABORATORY GUIDE TO ENZYMOLOGY An accessible guide to understanding the foundations of enzymology at its application in drug discovery Enzymes are highly specialized proteins necessary for performing specific biochemical reactions essential for life in all organisms. In disease, the functioning of these enzymes can become altered and, therefore, enzymes represent a large class of key targets for drug discovery. In order to successfully target dysfunctional enzymes pharmaceutically, the unique mechanism of each enzyme must be understood through thorough and in-depth kinetic analysis. The topic of enzymology can appear challenging due its interdisciplinary nature combining concepts from biology, chemistry, and mathematics. Laboratory Guide to Enzymology brings together the theory of enzymology and associated lab-based work to offer a practical, accessible guide encompassing all three scientific disciplines. Beginning with a brief introduction to proteins and enzymes, the book slowly immerses the reader into the foundations of enzymology and how it can be used in drug discovery using modern methods of experimentation. The result is a detailed but highly readable volume detailing the basis of drug discovery research. Laboratory Guide to Enzymology readers will also find: Descriptions of key concepts in enzymology Examples of drugs targeting different enzymes via different mechanisms Detailed discussion about many areas of enzymology such as binding and steady-state kinetics, assay development, and enzyme inhibition and activation Laboratory Guide to Enzymology is ideal for all pharmaceutical and biomedical researchers working in enzymology and assay development, as well as advanced students in the biochemical or biomedical sciences looking to develop a working knowledge of this field of research.

Enzymatic Analysis: A Practical Guide is a multipurpose manual of laboratory methods. It offers a systematic scheme for the analysis of biological materials from the level of the whole organ down to the single cell and beyond. It is intended as a guide to the development of new methods, to the refinement of old ones, and to the adaptation in general of methods to almost any scale of sensitivity. As some may realize, the book is a sequel to A Flexible System of Enzymatic Analysis, originally published in 1972. The major changes, other than an appropriate interchange of authors, consist of a wholly new chapter of methods and protocols for measuring enzymes, the addition of 13 new entries in the metabolite chapter, and a much superior chapter on enzymatic cycling. With considerable nostalgia, we have switched from DPN and TPN to NAD and NADP nomenclature, which no doubt will make Otto Warburg turn over in his grave. The incentives for the methodology in this book came from the rigorous demands of quantitative histochemistry and cytochemistry. These demands are specificity, simplicity, flexibility, and, of course, sensitivity—all likewise desirable attributes of methods for other purposes. The specificity is provided by the use of enzyme methods. Simplicity is achieved by leading all reactions to a final pyridine nucleotide step.
