Amino acid side chains act as nucleophiles and proton donors/acceptors in various enzymatic reactions. We will use them frequently in reactions during 40B, and therefore the purpose of this exercise is to review the properties of amino acid side chains you have learned in 40A.

Step 1
All amino acids have a central carbon atom (the alpha carbon) to which an amino group (NH2), a carboxyl group (COOH), a hydrogen atom, and a variable side chain (R group) are attached. The properties of an amino acid are primarily determined by its side chain. Show more…

Chymotrypsin selectively cleaves polypeptide chains on the carbonyl side of the amino acids phenylalanine and tyrosine. (a) Briefly explain the selective nature of chymotrypsin towards these amino acids. (b) Using the following substrate, show the enzymatic mechanism of chymotrypsin and discuss the kinetic behavior of the reaction.
