WebAn enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. An inhibitor can prevent a substrate from entering the active site of the enzyme or hindering catalysis. It was well known that carbonic anhydrase inhibitors (CAIs) bind to a catalytic Zn2+ ion in the active site of CA isoenzymes and block their activity [10 ... Webinhibitor is binding to the same site as the substrate. So, as is the case with high KM, it is necessary to have more substrate to achieve a higher reaction rate, since the substrate can outcompete for the binding sites. 2.
