Enzyme Function FUNCTION: Thrombin-like snake venom serine protease that coagulates fibrinogen by inducing a fast degradation of the alpha chain (FGA) from human citrated plasma, and a slow degradation of beta chain (FGB). Potently induces platelet aggregation in both platelet rich plasma and washed platelet preparations in a concentration-dependent fashion. Shows amidolytic activities. {ECO:0000269|PubMed:16729248}.
