Lysine carboxypeptidase (EC 3.4.17.3, carboxypeptidase N, arginine carboxypeptidase, kininase I, anaphylatoxin inactivator, plasma carboxypeptidase B, creatine kinase conversion factor, bradykinase, kininase Ia, hippuryllysine hydrolase, bradykinin-decomposing enzyme, protaminase, CPase N, creatinine kinase convertase, peptidyl-L-lysine(-L-arginine) hydrolase, CPN) is an enzyme.[1][2][3] This enzyme catalyses the following chemical reaction

Release of a C-terminal basic amino acid, preferentially lysine

This is a zinc enzyme found in plasma. It inactivates bradykinin and anaphylatoxins.
