Thrombin is a trypsin-like serine protease that is encoded by the F2 gene in humans. Thrombin is produced by the enzymatic cleavage of two sites on prothrombin by activated Factor X (Xa). Thrombin in turn acts as a serine protease that converts soluble
Prothrombin (coagulationfactorII) is produced in the liver and is post-translationally modified in a vitamin K-dependent reaction that converts ten glutamic acids on prothrombin into gamma-carboxyglutamic acid. Prothrombin is proteolytically cleaved to
