Abstract:
:Enzymatic functions are often altered during disease onset and progression, and therefore chemical-biological studies, which utilize chemical knowledge to discover novel protein functions, are often employed to find proteins with functions closely related to disease phenotypes. Such studies are known as forward chemical-biological approaches and form part of the emerging field of enzymomics (omics of enzymes). This review provides an overview of methodologies available for discovering and characterizing disease-related alterations of enzymatic functions and prospects for the future.
