Carboxypeptidase U (EC3.4.17.20, arginine carboxypeptidase, carboxypeptidase R, plasma carboxypeptidase B, thrombin-activatable fibrinolysis inhibitor) is an enzyme. This enzyme catalyses the following chemical reaction

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