Which amino acids have side chains that fit into the specificity pocket of chymotrypsin? arginine glycine tyrosine aspartate phenylalanine alanine

tyrosine and phenylalanine

Explanation:

Chymotrypsin is a mammalian digestive enzyme that catalyzes the hydrolysis of proteins in the small intestine. it is highly selective in its action as it hydrolyzes only those peptide bonds on the carboxyl side of AROMATIC AMINO ACIDS such as tyrosine, phenylanine, tryptothan.

Thus, of all listed tyrosine and phenylalanine are the amino acids.
