A metalloproteinase, named BaP1, was purified to homogeneity from the venom of Bothrops asper (Pacific region) of Costa Rica by ion-exchange chromatography on CM-Sephadex and gel filtration on Sephacryl S-200. The enzyme has a mol. wt of 24,000 and contains few Cys and high numbers of Asp, Leu, Ser and Glu. BaP1 hydrolyzes casein, hide powder azure and fibrinogen, having an optimal pH of 8.0. It rapidly digests the A alpha-chain of fibrinogen and, later on, the B beta-chain, leaving the gamma-chain unaffected. Chelating agents (EDTA and 1,10-phenanthroline) inhibited proteolytic activity, whereas 2-mercaptoethanol and soybean trypsin inhibitor did not affect this activity. BaP1 has a weak hemorrhagic activity, with a minimum hemorrhagic dose of 20 micrograms; this activity was inhibited by EDTA and was abolished after incubation at 60 degrees C. In addition, BaP1 induces edema and a mild myotoxic effect, lacking coagulant, defibrinating and lethal effects.
