Active site

... to the active site but cannot be processed by the enzyme. In noncompetitive inhibition , the inhibitor binds to the enzyme at another site, the allosteric site , and this causes a structural change in the enzyme such that the active site is rendered useless. Uncompetitive inhibition , is similar to ...

Insulin
