noncompetitive inhibition

biochemistry

Quick Summary

Noncompetitive inhibition occurs when an inhibitor binds to an enzyme at a location other than the active site. This binding changes the enzyme's shape, deforming the active site and preventing it from reacting with its substrate. Unlike competitive inhibition, the inhibitor does not prevent the substrate from binding to the enzyme. This type of inhibition is often a form of negative feedback, where the end product of a metabolic pathway acts as an allosteric inhibitor on an earlier enzyme in that pathway. Enzymes are biological catalysts that regulate chemical reactions in living organisms.12
