Indole is a competitive inhibitor of chymotrypsin. In the absence of the inhibitor, chymotrypsin will very slowly hydrolyze glycine residues in proteins, but will hydrolyze aromatic amino acids. In the presence of indole, chymotrypsin will hydrolyze glycine residues 10,000 times faster than in the absence of inhibitor, yet it will not hydrolyze aromatic amino acids at an appreciable rate. Explain. (Hint: consider the type of inhibition and the structures of the substrates and inhibitor).
