Physiol. Chem. [mod. f. Gr. θρόμβ-ος clot, THROMBUS + -ase, after diastase.] A synonym of thrombin (on the assumption that that is an enzyme).
1908. Bayliss, Nature of Enzymes, 73. According to Morawitz there exists in circulating blood a body ‘thrombogen,’ which can be converted by a ‘thrombokinase’ present in all tissues into a precursor of the enzyme which acts upon fibrinogen to form fibrin. This precursor, or prothrombase, is changed into the active thrombase by calcium ions.
