Abstract

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