CC   -!- FUNCTION: Damages membranes of susceptible bacteria. Has antibacterial
CC       activity against the Gram-positive bacteria B.megaterium and S.warneri.
CC       After 45 minutes of treatment with this protein, B.megaterium have no
CC       visible pili and are smooth. Has no antibacterial activity against the
CC       Gram-positive bacteria B.thuringiensis, S.aureus, S.clavuligerus and B.
CC       anthracis, or the Gram-negative bacteria E.coli and A.tumefaciens. Has
CC       no hemolytic activity. Does not inhibit the proteinases elastase and
CC       cathepsin G. Is not toxic to mice. {ECO:0000250|UniProtKB:P83952}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305|PubMed:18979207}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC       {ECO:0000305|PubMed:18979207}.
CC   -!- SIMILARITY: Belongs to the snake waprin family. {ECO:0000305}.
