EC 3.4.21.69

Accepted name: protein C (activated)

Reaction: Degradation of blood coagulation factors Va and VIIIa

Other name(s): blood-coagulation factor XIVa; activated blood coagulation factor XIV; activated protein C; autoprothrombin II-A; protein Ca; APC; GSAPC

Comments: A peptidase of family S1 (trypsin family), one of the γ-carboxyglutamic acid-containing coagulation factors. Formed from protein C, the proenzyme that circulates in plasma, by the action of a complex of thrombin with thrombomodulin, or by serine endopeptidases present in several snake venoms
