Reaction mechanism for the transamination of alanine based on this figure.
Chemical labeling of chymotrypsin by the compound tosylphenylalanine chloromethyl ketone (TPCK) modifies the His 57 in the
enzyme's active site. The structure of this derivative is shown below. TPCK inactivates the enzyme because the bulky addition
prevents it from cleaving nearby covalent bonds.
