Enzyme Information

3.4.21.6
Coagulation factor Xa.
based on mapping to UniProt P00742
Selective cleavage of Arg-|-Thr and then Arg-|-Ile bonds in prothrombin to form thrombin.
-!- A blood coagulation factor formed from the proenzyme factor X by limited proteolysis. -!- Factor X is a glycoprotein composed of a heavy chain and a light chain, which are generated from a precursor protein by the excision of the tripeptide RKR and held together by one or more disulfide bonds. -!- The activated factor Xa converts prothrombin to thrombin in the presence of factor Va, Ca(2+) and phospholipids. -!- Scutelarin (EC 3.4.21.60) has similar specificity, but does not require factor Va. -!- Belongs to peptidase family S1.
