| Official 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 |
| Comment(s) |
|---|
- 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 3.4.21.28, EC 3.4.21.29 and EC 3.4.21.30.
