Background

Carboxypeptidase A1 encoded by the CPA1 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 or branched aliphatic side chains including Phe, Tyr, Trp, Leu or Ile. It is important in the degradation of food proteins to produce essential amino acids such as Phe and Trp. The deduced amino acid sequence of human CPA1 consists of a signal peptide (residues 1 to 16), a pro region (residue 17 to 110), and a mature chain (residues 111 to 419). The purified rhCPA1 corresponds to the pro form which can be activated.
