WebGeneral representation of uncompetitive inhibition. Uncompetitive inhibition, also known as anti-competitive inhibition, takes place when an enzyme inhibitor binds only to the complex formed between the enzyme and the substrate (the E-S complex). Uncompetitive inhibition typically occurs in reactions with two or more substrates or products. WebJul 4, 2024 · Remember that non-competitive inhibitors aren't attaching directly to the active site, but elsewhere on the enzyme. The inhibitor attachs to a side group in the protein chain, and affects the way the protein folds into its tertiary structure. That in turn changes the shape of the active site. latest on lysa terkeurstWebIt is a form of an enzyme inhibition where binding of the inhibitor to the active site on the enzyme prevents binding of the substrate.

"WebNoncompetitive inhibitors don’t prevent the substrate from binding to the enzyme. In fact, the inhibitor and substrate don't affect one another's binding to the enzyme at all. However, when the inhibitor is bound, the enzyme cannot catalyze its reaction to produce a product. " - How do non competitive inhibitors work
