Contents

Russell's viper venom serine proteinase, RVV-V (closed-form)

Template:ABSTRACT PUBMED 21871889

Function

[VSPG_DABSI] Venom serine protease that selectively activates factor V (F5) in a calcium-independent manner. It cleaves the Arg(1545)-Ser(1546) linkage in the human factor V molecule. Induces the coagulation of mammalian plasma.[1]

About this Structure

3s9a is a 1 chain structure with sequence from Daboia russellii siamensis. Full crystallographic information is available from OCA.
