thrombin
thrombin A proteolytic enzyme, involved in the clotting of blood, that is generated by the conversion of its zymogen prothrombin, the process being activated by the enzyme thromboplastin, in the presence of calcium ions, and other factors. Thrombin acts upon the soluble fibrinogen in blood to produce insoluble fibrin by catalysing the removal of the fibrinopeptides A and B from fibrinogen. See also BLOOD CLOTTING; BLOOD PLASMA.
