CC   -!- FUNCTION: Acts as a metalloprotease. Penetrates intact tissue and
CC       specifically cleaves the vesicle-associated membrane protein 2 (VAMP2)
CC       (part of the SNARE complex) involved in pancreatic secretion, thus
CC       disrupting the normal vesicular traffic (By similarity). {ECO:0000250}.
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC   -!- ACTIVITY REGULATION: Inhibited by EDTA. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- SIMILARITY: Belongs to the venom metalloproteinase (M12B) family.
CC       {ECO:0000305}.
