Enzyme Function | FUNCTION: Thrombin-like snake venom serine protease. Displays a specificity similar to trypsin. Releases only fibrinopeptide A in the conversion of fibrinogen (FGA) to fibrin (By similarity). Shows coagulant, esterase and amidase activities. Reversibly increases the permeability of the blood brain barrier (BBB) in mice. Induces the barrel rotation syndrome in mice, which is manifested by gyroxin-like, rapid rolling motions. This syndrome may be due to its effect on BBB permeability, and certainly also to other actions affecting endogenous substrates present in the endothelium, nervous tissues or blood. {ECO:0000250, ECO:0000269|PubMed:11137545, ECO:0000269|PubMed:19341755, ECO:0000269|PubMed:20637222}. |
