Thrombin-like snake venom serine protease, with high clotting activity in vitro. Has also fibrinogenolytic ability, showing a fast degradation of fibrinogen Aalpha chain (FGA), a slow degradation of Bbeta chain (FGB) and no degradation of gamma chain. Also causes platelet aggregation in platelet rich plasma (PRP) and washed platelet suspension. Strongly inhibited by PMSF and slightly inhibited by EDTA and soybean trypsin inhibitor. Optimum pH is 8.0. Optimum temperature is 45 degrees Celsius. Monomer. Expressed by the venom gland. Contains both N-linked carbohydrates and sialic acid. Belongs to the peptidase S1 family. Snake venom subfamily. Ile, Leu, Gln and Lys residues were impossible to discriminate with the method employed and are all assigned by comparison with orthologs.
