FIG. 1.

Schematic drawing of the rokA region, including the predicted promoter. The rokA gene is located upstream of and divergent from a possible ABC transporter of unknown function. A schematic of the region of the rokA deletion mutants CJB100 and CJB101 and the inserts of the rokA-containing plasmids pBFROK10 and pBFROK40 are shown. Shown above is a portion of the intergenic region containing a predicted promoter for the rokA gene, including the N-terminal methionine as confirmed by sequencing of pure RokA protein.
