Multifunctional venom serine protease that has fibrino(geno)lytic activity towards the A alpha-chain of human fibrinogen (FGA) and a slow activity towards the B beta-chain (FGB). Also hydrolyzes bovine low-molecular-mass kininogen and releases bradykinin. Catalyzes the hydrolysis of BAEE, S-2238 and S-2302. Inhibited by PMSF and soybean trypsin inhibitor. Partially inhibited by L-cysteine and DTT. Not affected by EDTA. Monomer. Expressed by the venom gland. Glycosylated; contains 35.8% neutral carbohydrate. The enzyme does not catalyze S-2251 (a plasminogen activator substrate). Has little effect on digesting gamma-chain of fibrinogen. Belongs to the peptidase S1 family. Snake venom subfamily.
