KEGG ENZYME: 3.4.21.6

ENZYME: 3.4.21.6

Entry

EC 3.4.21.6                 Enzyme

Name

coagulation factor Xa;
thrombokinase;
prothrombase;
prothrombinase;
activated blood-coagulation factor X;
autoprothrombin C;
thromboplastin;
plasma thromboplastin;
factor Xa;
activated Stuart-Prower factor;
activated factor X

Class

Hydrolases;
Acting on peptide bonds (peptidases);
Serine endopeptidases

Reaction(IUBMB)

Selective cleavage of Arg!Thr and then Arg!Ile bonds in prothrombin to form thrombin

Comment

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, Ca2+ and phospholipids. Scutelarin (EC 3.4.21.60) has similar specificity, but does not require factor Va.

History

EC 3.4.21.6 created 1972, modified 2011
