3.4.24.49	additional information	comparison of hemorrhagic, caseinolytic and fibrinogenolytic activities of metalloproteinases HF3, bothropasin, the DC protein and metalloproteinase BJ-PI. Hemorrhagic activity of bothropasin is 0.006 mg to produce a hemorrhagic area of 1 cm2. Fibrinogenolytic activity of bothropasin is 9.8 units/mg
