Activity Regulation ACTIVITY REGULATION: Inhibited by diisopropylfluorophosphate (DFP), but not by hirudin. {ECO:0000269|PubMed:8110787}.
Binding Site
Calcium Binding
catalytic Activity CATALYTIC ACTIVITY: Reaction=Selective cleavage of Arg-|-Xaa bond in fibrinogen, to form fibrin, and release fibrinopeptide A. The specificity of further degradation of fibrinogen varies with species origin of the enzyme.; EC=3.4.21.74;
DNA Binding
EC Number 3.4.21.74
Enzyme Function FUNCTION: Thrombin-like snake venom serine protease that clots fibrinogen by releasing fibrinopeptide A from the alpha chain of fibrinogen (FGA), induces platelet aggregation through its interaction with GPIb (GP1BA/GP1BB), and activates factor VIII (F8). {ECO:0000269|PubMed:8110787}.
Temperature Dependency
PH Dependency BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 7.4-8.0 for the clotting activity. {ECO:0000269|PubMed:8110787};
Pathway
