microcin J25

antibioticmech:aro-0a1c492c45 ·ANTIBACTERIAL ·MINTED SEEDED

Microcin J25 is a peptide antibiotic that inhibits transcription by bacterial RNA polymerase. MccJ25 is produced by Escherichia coli strains that harbor a plasmid-borne antibiotic-synthesis and antibiotic-export cassette, consisting of a gene for MccJ25 precursor (a 58 residue linear peptide), two genes for factors that process MccJ25 precursor into MccJ25, and one gene for export of MccJ25. — PMID:15200952
