Comparison of the oppA/brnQ operon in different strains. The region of the oppA/brnQ operon within the ATCC 3502 strain was compared in the different strains. The horizontal arrows indicate coding sequences (CDSs). Gene designations are labelled above the arrow. GenBank locus IDs are labelled below the arrow. The first CDS was given the full GenBank locus ID followed by an abbreviated ID that uses only the last two to three digits. In this region (895 - 915 kb) the bont/a1 within the ATCC 3502 strain and the bont/(b) of the A1(B) strain are located. No bont genes within the other strains of Langeland, Kyoto-F, 657, Okra and Loch Maree are located here. The regions flanking the oppA/brnQ operon are similar upstream and downstream in each of these strains.
