Evidence that colicin X is microcin B17.


The DNA replication inhibitor microcin B17 is a peptide antibiotic produced by Escherichia coli strains carrying plasmid pMccB17. Here we present evidence that antibiotic activities previously named colicin X are probably identical to microcin B17. Our results include comparison of the conditions of production of the antibiotics, their mode of action, cross… (More)
