别名:Arginine Carboxypeptidase; Carboxypeptidase R; Plasma Carboxypeptidase B (Misleading, Since The Term Carboxypeptidase B Is Used For Other Enzymes); Thrombin-Activatable Fibrinolysis Inhibitor
本酶催化的反应为Release Of C-Terminal Arg And Lys From A Polypeptide,(人类)血浆中的羧肽酶U前体在凝血过程中被凝血酶或纤溶酶激活,形成不稳定的羧肽酶U,其活性与更稳定的赖氨酸羧肽酶相似,只是对Lys不表现出优于Arg的偏好。一种锌酶,属于肽酶家族M14(羧肽酶A家族)。
