Known from venom of?Vipera russelli. Inhibited by di-isopropyl fluorophosphate, unlike the metallopeptidase russellysin (EC?3.4.24.58) that is specific for factor X [1]. In peptidase family?S1?(trypsin family) [2]. |

| Reactions |
Fully activates human clotting factor V by a single cleavage at the 1545- Trp-Tyr-Leu-Arg-|-Ser-Asn-Asn-Gly-1552 bond. Cattle, but not rabbit, factor V is cleaved, and no other proteins of the clotting system are attacked. Esterase activity is observed on Bz-Arg-OEt and Tos-Arg-OMe, and amidase activity on Phe-pipecolyl-Arg-NHPhNO(2). |
