WebAn enzyme inhibitor is a molecule that binds to an enzyme and blocks its activity. Enzymes are proteins that speed up chemical reactions necessary for life, in which substrate molecules are converted into products. An enzyme facilitates a specific chemical reaction by binding the substrate to its active site, a specialized area on the enzyme that accelerates … Web• Over recent years there has been a resurgence in the focussed development of irreversible inhibitors that act via a covalent, time-dependent mechanism. Traditionally the potential for enzyme inhibition has been determined by steady state affinity measurements and quantified in terms of IC 50. However this parameter in isolation may be

WebA systematic kinetic analysis of irreversible inhibition of these enzyme reactions is presented. Based on the algebraic criteria proposed in this work, it should be possible to evaluate either the mechanism of inhibition (complexing or non-complexing), or the type of inhibition (competitive, non-competitive, uncompetitive, mixed non-competitive).
