A 40 kb region present in Rd KW20 shows two blocks of genomic variation among other strains. The upstream block is bounded on the right by a frame-shifted insertion sequence (IS) element (HI1018). The downstream block (HI1024-HI1032) includes genes with likely roles in sugar transport and metabolism. Rd is used as a reference for the alignment, and sequence present in other strains without homology to Rd is not shown.
