Uncompetitive inhibitors bind only to the enzyme-substrate complex and not to the free enzyme.

#Unit 1. Molecules and their Interaction Relevant to Biology

In neither case does the inhibitor compete with the substrate for the same binding site, so the inhibition cannot be overcome by increasing the substrate concentration.

Substrate-binding could cause a conformational change to take place in the enzyme and reveal an inhibitor binding site, or the inhibitor could bind directly to the enzyme-bound substrate.
