KEGG   ENZYME: 3.4.17.20Help
Entry
EC 3.4.17.20                Enzyme                                 
Name
carboxypeptidase U;
arginine carboxypeptidase;
carboxypeptidase R;
plasma carboxypeptidase B (misleading, since the term carboxypeptidase B is used for other enzymes);
thrombin-activatable fibrinolysis inhibitor
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Metallocarboxypeptidases
BRITE hierarchy
Reaction(IUBMB)
Release of C-terminal Arg and Lys from a polypeptide
Comment
Pro-carboxypeptidase U in (human) plasma is activated by thrombin or plasmin during clotting to form the unstable carboxypeptidase U, with activity similar to that of the more stable lysine carboxypeptidase, except that no preference is shown for Lys over Arg. A zinc enzyme, in peptidase family M14 (carboxypeptidase A family)
Orthology
