Antimicrobial peptide which assumes an amphiphilic alpha-helix conformation upon contact with membranes (PubMed:19591185). Insertion into membranes involves Trp-3 (By similarity). Penetrates into cells once membrane has been permeated (By similarity). Active against Gram-negative bacteria E.coli (MIC=1.7 uM), P.aeruginosa (MIC=15.8 uM) and Gram-positive bacteria S.aureus (MIC=14.3 uM) and B.subtilis (MIC=0.8 uM). Has cytotoxic but no hemolytic activity (PubMed:19591185). Binds DNA in vitro (By similarity). Expressed by the venom gland. The C-terminal amidation is required for full activity.
