Thrombin-like snake venom serine protease that induces blood clotting in vitro, defibrinogenation in vivo (by intraperitoneal injection into mice), albuminolytic and fibrinogenolytic activities. Preferentially cleaves the alpha chain of fibrinogen (FGA). Causes hemolysis in the heart, causes apparent hyperemia and lymphocytic interstitial pneumonitis in the lung, causes necrosis and inflammatory infiltrate in the liver, and causes glomerular congestion in the kidney. Also provokes a drastic myonecrosis. Inhibited by benzamidine and partially inhibited by EDTA. Optimum pH is 7.0-8.0. Optimum temperature is 30-40 degrees Celsius. Monomer. Expressed by the venom gland. Does not present azocaseinolytic activity (PubMed:20184912). Does not provoke vascular lesions or hemorrhage. Belongs to the peptidase S1 family. Snake venom subfamily. Lacks the typical His and Asp active sites in position 65 and 112, which are replaced by an Asn and Thr residues, preventing the protease activity. The sequence corresponding to the activity described in PubMed:20184912 may be slightly different from the sequence shown.
