Alternative Name(s)
factor V-activating proteinase.
RVV-V component.
Reaction catalysed
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-NHPhNO2
