Uptake and Mode of Action of the Peptide Antibiotic Microcin B1787). The genes involved in the biosynthesis and secretion of this antibiotic as well as in the regulation of its production are described in an accompanying paper (Moreno ., 1991). MccB 17 is a glycine-rich peptide of about 3,200 daltons (Davagnino .., 1986). It inhibits semiconservative DNA replica

In addition, the bactericidal activity of many strains appeared to result from bacteriocin production (Klaenhammer, 1988). Although bacteriocins of lactic ac
