(a) Interpretation: Role of Glu 270 in catalysis in the mechanism of carboxypeptidase A should be identified. Concept introduction: Glutamine can also be denoted as Glu 270.It is a general base catalyst in 1 s t step and helps in the catalysis of base whereas it act as general acid catalyst in another step. Glutamine consists of carboxyl group which attacks the hydroxyl of Zn 2 + and thus, it act as a base catalyst that turns into carboxyl group whereas arginine contains ammonium ion which helps in the ionic interaction with the carboxypeptidase. Carboxypeptidase is an enzyme helps in hydrolysis of peptide of proteins and thus converting trypsinogen to trypsin and chymotrypsinogen to chymotrypsin.
