WebApr 12, 2024 · Non-competitive inhibition can occur in the presence or absence of the substrate as non-competitive inhibitors can bind equally well to the enzyme and enzyme–substrate complex. Uncompetitive inhibition. In uncompetitive inhibition, a chemical (enzyme inhibitor) binds only to the substrate-enzyme complex. WebAn example of a competitive inhibitor is the antineoplastic drug methotrexate. Methotrexate has a structure similar to that of the vitamin folic acid (Fig. 4-5).
