UniProtKB description:  Channel-forming bacteriocin. Forms cation-selective channels. Active on enterobacteria, with highest activity against E.coli. Not active on other Gram-negative bacteria, Gram-positive bacteria or fungi. The unmodified protein is active against E.coli and S.enteritidis. When the siderophore ester is present at Ser-99, antibacterial activity against these species is increased and activity is also detected against E.cloacae and K.pneumoniae. Neutralized by its immunity protein MceB (PubMed:9864332).
