The transcription unit diagram for the E. coli bglGFB operon, showing regulation by a variety of transcription factors and attenuation by BglG. The diagram is not to scale; rather, the regulatory region has been expanded to show detail with the genes compacted. Sites shown in green activate and sites shown in magenta inhibit transcription. The location of the StpA binding site is unknown.
