FIG. 2.

Relevant chromosomal region of the S. enterica chromosome. Presented is a representation of the chromosomal region of interest. Positions of the insertions that were linked to the lesion allowing utilization of AIRs in DM2253, as determined by sequencing, are indicated. The only insertions that eliminated the ability of DM2253 to utilize AIRs were those located in stm4065 or stm4066. The surrounding genes, as annotated (genome.wustl.edu/gsc/Projects/S.typhimurium), are indicated. STM designations are used for the products of ORFs that are not found in E. coli and that have not been annotated.
