Fig 7.

Effects of glucose addition on P2 promoter. Cells were grown in sporulation medium without (closed symbols) or with (open symbols) 2% (wt/vol) glucose. Each fusion is indicated above the relevant panel. (A) Circles, wild-type cells; triangles, glnA cells. Schematic representations of the structure of U-P2 and the regulation of P2 are shown alongside the panel. Numbers indicate nucleotide positions relative to the transcription start site for P3. (B) Circles, wild-type cells; triangles, tnrA cells. (C) Circles, degU cells. Schematic representations of the regulation of the U-WT fusion bearing the P2 and P3 promoters are shown alongside the panel. Numbers indicate nucleotide positions relative to the transcription start site for P3.
