Examples of competitive enzyme inhibitors

WebCompetitive inhibition is usually caused by substances that are structurally related to the substrate, and thus combine at the same binding site as the substrate. The bindings are exclusive to each other, forming either an enzyme–substrate (ES) or an enzyme–inhibitor (EI) complex but not a ternary complex (EIS) (Scheme 1.3, Fig. 1.3).This type of … WebJun 3, 2024 · Enzyme Inhibitors- Competitive, Noncompetitive, End-product inhibition. 1.
