Venombin A (EC 3.4.21.74, alpha-fibrinogenase, habutobin, zinc metalloproteinase Cbfib1.1, zinc metalloproteinase Cbfib1.2, zinc metalloproteinase Cbfib2, ancrod) is an enzyme.[1][2][3][4][5] This enzyme catalyses the following chemical reaction

Selective cleavage of Arg- bond in fibrinogen, to form fibrin, and release fibrinopeptide A. The specificity of further degradation of fibrinogen varies with species origin of the enzyme

This enzyme is a thrombin-like enzyme from venoms of snakes of the viper/rattlesnake group.
