Application
Factor V activating enzyme from Russell′s viper venom (RVV) is a single-chain glycoprotein that is involved in the rapid clotting of blood. Factor V circulates in the blood as an inactive cofactor and must be activated by proteases such as Factor V activating enzyme from RVV . This product may be useful in studying the blood coagulation cascade as well as the inherited deficiency called parahemophilia .
Biochem/physiol Actions
Factor V activator for RVV contains fucose, mannose, galactose, glucosamine, and neuraminic acid. Factor V activating enzyme from RVV is an arginine esterase that is sensitive to diisopropyl fluorophosphate (DFP) .
Physical form
Stabilized in albumin and sodium chloride.
Other Notes
One unit will increase the Factor V activity in 0.1 mL of fresh normal human plasma by at least 2× after incubation for 3 min at 37 °C.

Constituents of platelet membranes regulate the activity of the prothrombinase complex. We demonstrate that membranes containing phosphatidylcholine and phosphatidylethanolamine (PE) bind factor Va with high affinity (K(d) = ∼10 nm) in the absence of phosphatidylserine (PS). These membranes support formation
