Background: Carboxypeptidase A2/CPA2

Carboxypeptidase A2 encoded by the CPA2 gene cleaves the C-terminal amide or ester bond of peptides that have a free C-terminal carboxyl group (1). It prefers the C-terminal residues with aromatic side chains including Phe, Tyr, and Trp. The deduced amino acid sequence of human CPA2 consists of a signal peptide (residues 1 to 16), a pro region (residues 17 to 112), and a mature chain (residues 113 to 417). The purified rhCPA2 corresponds to the pro form, which can be activated and assayed.
