CPA4, also known as carboxypeptidase A4, is a secreted, zinc-dependent metallocarboxypeptidase that removes the C-terminal amino acid from peptides having a free C-terminal carboxyl group. CPA4 is synthesized as zymogens that are activated by proteolytic cleavage.
Source:Recombinant protein corresponding to aa17-421 from human CPA4, fused to His-Tag at C-terminal, expressed in insect cell.
