Has antibacterial activity against Gram-positive bacteria B.megaterium Bm11, S.lentus and M.luteus, Gram-negative bacteria Y.pseudotuberculosis YP III and P.syringae pv tabaci, and antifungal activity against C.tropicalis, C.guiller-mondii and P.nicotianae spores. Has hemolytic activity. The mature peptide inserts into the hydrophobic core of the bacterial cell membrane and increases permeability without disrupting membrane integrity. Probably binds to the outer membrane surface before aggregating to form transmembrane pores
