Insecticidal and antimicrobial peptide. Has insecticidal activity against larvae of flesh fly S.carnaria. Has antibacterial activity against Gram-positive bacterium B.subtilis B-501 (MIC=1.25 uM) and Gram-negative bacterium E.coli DH5alpha (MIC=2.5 uM). Expressed by the venom gland. Both the N-terminus (1-33) and the C-terminus (38-69) of the mature peptide form alpha-helices which probably disrupt target cell membranes. The linker region (34-37) probably derives from a processing quadruplet motif (PQM), found in propeptides of many zodatoxins, hinting at a fusion of two originally separate membrane-active peptides. LD(50) is 40 ug/g in larvae of flesh fly S.carnaria. Belongs to the cationic peptide 06 (cytoinsectotoxin) family.
