Enzyme Inhibitors
EditEnzyme inhibitors are substances that reduce enzyme activity by interacting with an enzyme or a state of its catalytic cycle. Reversible binding can obstruct substrate association or alter the ability of a substrate-bound enzyme to complete turnover. The relationship between inhibitor binding and the reaction sequence produces characteristic inhibition kinetics [1][2]. Covalent inhibitors possess chemical groups capable of forming a bond with a residue in the target protein [3]. Their selectivity can be assessed across multiple enzymes by measuring competition with activity-based probes, which report accessible, reactive enzyme sites [4]. Recognition interactions position the inhibitor near a susceptible residue, while the inhibitor's reactive group participates in bond formation. Together, these features determine the target engagement and persistence of covalent inhibition [5].
