EC 3.4.17.22

Accepted name: metallocarboxypeptidase D

Reaction: Releases C-terminal Arg and Lys from polypeptides

Other names: carboxypeptidase D (cattle, human, mouse, rat); gp180 (duck)

Comments: Activated by Co2+; inhibited by guanidinoethylmercaptosuccinic acid. Large molecule (180 kDa) because of presence of three copies of metallopeptidase domain. The product of the silver gene (Drosophila) is similar. A zinc metallopeptidase in peptidase family M14 (carboxypeptidase A family)
