ENZYME entry: EC 3.4.21.69

PURL: https://purl.expasy.org/enzyme/EC/3.4.21.69
Accepted Name
activated protein C (thrombin-activated peptidase)
Alternative Name(s)
activated blood coagulation factor XIV
autoprothrombin IIA
protein C (activated)
Reaction catalysed
Degradation of blood coagulation factors Va and VIIIa
Comment(s)
  • One of the gamma-carboxyglutamic acid-containing coagulation factors.
  • The enzyme plays an important role in regulating anticoagulation, inflammation, and cell death by proteolytically inactivating the blood coagulation factors factor Va and factor VIIIa.
  • Formed from protein C, the proenzyme that circulates in plasma, by the action of a complex of thrombin with thrombomodulin.
  • Protein C can also be activated by serine endopeptidases present in several snake venoms.
  • Belongs to peptidase family S1.
