Carboxypeptidase which preferentially cleaves C-terminal acidic residues from peptides and proteins. Can also cleave C-terminal hydrophobic amino acids, with a preference for small residues over large residues. Strongly inhibited by potato carboxypeptidase inhibitor, and the chelating agents EDTA and 1,10-phenanthroline. Also inhibited by compounds with multiple carboxylic acid groups such as citrate and succinate, and to a lesser exent the amino acids aspartate and glutamate. Not significantly inhibited by benzylsuccinic acid. Detected in enterocytes of the ileum. N-glycosylated. Belongs to the peptidase M14 family.
