Appendix 4—figure 1. Two cases in which we see transcription-factor-binding sites that we have found to regulate both of the two divergently transcribed genes.

(A) An information footprint and regulatory cartoon for the divergently transcribed bdcA and bdcR promoters. A single NsrR site regulates both promoters. (B) An information footprint and regulatory cartoon for the ilvC and ilvY promoters. Both promoters are repressed by IlvY when grown without acetolactate. Only the IlvY site is labeled on the information footprint.
