Webinhibitor is binding to the same site as the substrate. So, as is the case with high KM, it is necessary to have more substrate to achieve a higher reaction rate, since the substrate can outcompete for the binding sites. 2. Uncompetitive Inhibition In the case of uncompetitive inhibition, the inhibitor binds to the E-S complex and Websubstrate inhibition: inhibition of an enzyme activity by a substrate of the reaction catalyzed by that enzyme; often, this type of inhibition occurs at elevated substrate concentrations …
