| Comments | 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) (formerly EC?3.4.21.28) [1], batroxobin from?Bothrops atrox?(South American pit viper) (formerly EC?3.4.21.29) [2, 5] and crotalase from?Crotalus adamanteus?(Eastern diamondback rattlesnake) (formerly EC?3.4.21.30) [3, 4]. In peptidase family?S1?(trypsin family). Does not require activation by Ca2+. |
