Localization of the regulator binding sites of PobR, PcaU, MhpR, PcaR, and GenR. TSSs and transcriptional directions of the target genes are indicated with the thin arrows. The −10 and −35 regions are marked, and the regulator primary binding sites are highlighted in black squares. The large arrows indicate the direction of transcription of each operon (filled, structural genes; open, regulatory genes).
