Enzyme Function FUNCTION: Thrombin-like snake venom serine protease. Cleaves fibrinogen (beta chain of fibrinogen (FGB) and more slowly alpha chain (FGA)) without inducing fibrin clotting and cleaves kininogen to produce bradykinin (KNG), resulting in the reduction of blood pressure. {ECO:0000269|PubMed:9546675}.
