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) .

Unit Definition

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.

Physical form

Stabilized in albumin and sodium chloride.

Blood coagulation factor V (FV) is a multifunctional protein that circulates in human plasma as a precursor molecule which can be activated by thrombin or activated factor X (FXa) in order to express its cofactor activity in prothrombin activation. FV

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
