Web7 jul. 2024 · In mixed inhibition, the inhibitor binds to an allosteric site, i.e. a site different from the active site where the substrate binds. However, not all inhibitors that bind at allosteric sites are mixed inhibitors. In uncompetitive inhibition, the inhibitor binds only to the enzyme-substrate complex.
