FIG. 3.

Possible OxyR-dependent repression of gntP and uxuAB; b2653, ygaQ, ygaR, and b2656; and ybjC, nfsA/mdaA, and rimK. The gene organization of the corresponding operons is shown. Predicted OxyR binding sites (41) of 7.0 bits centered at position 4549044, 8.8 bits centered at position 2784053, and 5.4 bits centered at position 2784276 are underlined. The confirmed OxyR binding site upstream of the grxA promoter (39) is indicated by the black boxes. The transcription starts documented for grxA and predicted for ybjC are denoted by solid and dotted arrows, respectively. The induction ratios observed for the wild-type and ΔoxyR mutant strains in the microarray experiment are given below each gene.
