ENZYME entry: EC

Accepted Name
Venombin A.
Reaction catalysed
Selective cleavage of Arg-|-Xaa bond in fibrinogen, to form fibrin, and release fibrinopeptide A. The specificity of further degradation of fibrinogen varies with species origin of the enzyme
  • A somewhat thrombin-like enzyme from venoms of snakes of the viper/rattlesnake group.
  • Species variants of the enzyme include ancrod from Agkistrodon rhodostoma (Malayan pit viper), batroxobin from Bothrops atrox (South American pit viper) and crotalase from Crotalus adamanteus (Eastern diamondback rattlesnake).
  • Does not require activation by calcium.
  • Belongs to peptidase family S1.
  • Formerly EC, EC and EC
