Carboxypeptidase U

Carboxypeptidase U (, arginine carboxypeptidase, carboxypeptidase R, plasma carboxypeptidase B, thrombin-activatable fibrinolysis inhibitor) is an enzyme. This enzyme catalyses the following chemical reaction


 * Release of C-terminal Arg and Lys from a polypeptide

Pro-carboxypeptidase U in (human) plasma is activated by thrombin or plasmin during clotting to form the unstable carboxypeptidase U.
