Thrombin-like snake venom serine protease that clots fibrinogen (FGA) by releasing only fibrinopeptide A. Also releases bradykinin from bovine low-molecular-mass kininogen (KNG). Monomer. Expressed by the venom gland. This protein seems to be found in adult B.jararaca venom but not in newborn snake venom. Belongs to the peptidase S1 family. Snake venom subfamily.
