coagulation factor Xa
Function:
- vitamin K-dependent serine protease
- proteolytically activates prothrombin in the presence of factor Va, Ca+2 & phospholipid during blood clotting
- selective cleavage of Arg-|-Thr & then Arg-|-Ile bonds in prothrombin to form thrombin
Pharmacology:
- factor Xa inhibitors are used as anticoagulant in prophylaxis for venous thromboembolism
