The movement of a tyrosyl residue in carboxypeptidase A when its substrate binds is an example of
A) substrate strain.
B) induced fit.
C) acid-base catalysis.
D) covalent catalysis.
E) stabilization of the transition state.

Question

Quizplus · Accepted Answer

The movement of the tyrosyl residue in carboxypeptidase A when its substrate binds is an example of induced fit. This is because the tyrosyl residue changes its conformation to fit the substrate, leading to the formation of the enzyme-substrate complex.
