This volume explores detailed methods and experimental protocols evaluating the effect of a compound or a mixture of compounds on the action of enzymes that are significant targets in pharmaceuticals. Consisting of three sections, the book delves into recent biocomputing and bioinformatics protocols, state-of-the art modern biophysical, electrophoretic, and chromatographic methods and high-throughput screening approaches, as well as detailed protocols and examples of the inhibition analysis and evaluation of selected enzymes. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
