Thrombin-like enzyme that induces the formation of fibrin clot. Cleaves the Aalpha-chain of fibrinogen (FGA) with higher activity than the Bbeta-chain (FGB). Induces platelet aggregation in both platelet-rich plasma and in washed platelet preparations. This aggregation is strongly inhibited by preincubation of the enzyme with PMSF. Inhibited by PMSF, disodium-EDTA, S(Dm) and soybean trypsin inhibitor (SBTI). SBTI and S(Dm) (the anti-hemorrhagic protein) acts as non-competitive inhibitors that decrease the enzymatic activity. Optimum pH is 8.0. Optimum temperature is 38-40 degrees Celsius. Monomer. Expressed by the venom gland. Homologous thrombin-like enzymes are N-glycosylated. This enzyme does not contain the consensus glycosylation sites, suggesting it is not glycosylated. Has no activity on the gamma-chain of fibrinogen (FGG). In vivo, does not induces a significant edema activity in mice (PubMed:19931298). Belongs to the peptidase S1 family. Snake venom subfamily.
