CC -!- FUNCTION: Factor Xa is a vitamin K-dependent glycoprotein that converts
CC prothrombin to thrombin in the presence of factor Va, calcium and
CC phospholipid during blood clotting. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Selective cleavage of Arg-|-Thr and then Arg-|-Ile bonds in
CC prothrombin to form thrombin.; EC=3.4.21.6;
CC -!- SUBUNIT: Heterodimer of a light chain and a heavy chain; disulfide-
CC linked. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Plasma; synthesized in the liver.
CC {ECO:0000269|PubMed:16706981}.
CC -!- PTM: Gamma-carboxyglutamate residues are formed by vitamin K dependent
CC carboxylation. These residues are essential for the binding of calcium.
CC -!- PTM: The activation peptide is cleaved by factor IXa (in the intrinsic
CC pathway), or by factor VIIa (in the extrinsic pathway). {ECO:0000250}.
CC -!- PTM: The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate
CC and asparagine is (R) stereospecific within EGF domains. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase S1 family. {ECO:0000255|PROSITE-
CC ProRule:PRU00274}.
