Bothrops snake venom metalloproteinase (SVMP)

Bothrops snake venom metalloproteinases (SVMPs) are the primary toxic enzymes found in the venom of pit vipers belonging to the Bothrops genus, such as Bothrops asper and Bothrops jararaca (Gutiérrez et al., 2016, Toxins). These zinc-dependent enzymes are classified into the reprolysin family (M12B) and are the chief agents responsible for the local and systemic pathologies observed in snakebite victims, including rapid tissue necrosis, massive hemorrhage, and consumptive coagulopathy (UniProt, 2023). SVMPs function by degrading essential components of the extracellular matrix and vascular basement membrane, such as type IV collagen, laminin, and fibronectin, which leads to capillary rupture and bleeding (PubMed, PMID: 16061020). Beyond their structural degradation roles, they also interfere with the coagulation cascade and platelet function, exacerbating systemic hemorrhage. Therapeutic intervention primarily relies on animal-derived antivenoms that contain neutralizing antibodies, though research is increasingly focused on small-molecule inhibitors like Batimastat and metal chelators that target the catalytic zinc ion to prevent permanent tissue damage (ClinicalTrials.gov, 2024). Understanding the diversity of SVMP classes (P-I to P-III) is critical for developing more effective, broad-spectrum treatments for Bothrops envenomation, which remains a major public health challenge in Latin America (WHO, 2021).
