enzyme inhibitor

a molecule that prevents an enzyme from catalysing a reaction. Such inhibitors can compete with the normal substrate (see COMPETITIVE INHIBITION or can block the active site, preventing entry of the substrate (see NONCOMPETITIVE INHIBITION). Inhibition may be reversible or irreversible. Enzyme inhibitors often form part of a FEEDBACK MECHANISM to regulate a biochemical pathway.
