| Enzyme Function | FUNCTION: [Snake venom metalloproteinase]: Has fibrinolytic activity. The recombinant enzyme cleaves both alpha- (FGA) and beta-chains (FGB) of fibrinogen, but not the gamma-chain. The recombinant protein does not produce hemorrhage in mice and does not have effect on ADP- or collagen-stimulated platelet aggregation. {ECO:0000269|PubMed:19375443}.; FUNCTION: [Disintegrin beta subunit]: Inhibits platelet aggregation induced by ADP, thrombin, platelet-activating factor and collagen. Acts by inhibiting fibrinogen interaction with platelet receptors GPIIb/GPIIIa (ITGA2B/ITGB3) (By similarity). {ECO:0000250}. |
