A small open reading frame from the Escherichia coli
chromosome, bcrCEC, encodes a homologue to the
BcrC subunit of the bacitracin permease from Bacillus
licheniformis. We show that disruption of the chromosomal
bcrCEC gene causes bacitracin sensitivity and, conversely, that BcrCEC confers bacitracin resistance when
expressed from a multicopy plasmid.
