Enzyme Function FUNCTION: Snake venom serine protease that shows non-specific action on fibrinogen (PubMed:30145175). It preferentially degrades fibrinogen Aalpha (FGA), releasing fibrinopeptide A, and shows a lower activity on fibrinogen Bbeta (FGB), releasing fibrinopeptide B and other uncommon fibrinopeptides (PubMed:30145175). Also shows low fibrinolytic activity compared to plasmin (PubMed:30145175). Has high enzymatic activity on the substrates for activated protein C and factor XIa, and for thrombin (PubMed:30145175). Shows a wide activity spectrum at different peptide sequences, with a preferential cleavage at Lys-|-Xaa over Arg-|-Xaa bonds (PubMed:30145175). {ECO:0000269|PubMed:30145175}.
Temperature Dependency BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Optimum temperature is 50 degrees Celsius. {ECO:0000269|PubMed:30145175};
