Fig. S1. Determination of transcription start sites of pegB, pegA and pegR. The nucleotide sequences of the pegB, the pegA and the pegR promoter regions are shown in (a), (b) and (c), respectively. The transcription start sites, which were determined by 5'-RACE, are indicated by the angled arrow for pegB and pegR and the dashed angled arrow for pegA. In (b), the angled arrow shows the pegA transcription start site determined by primer extension analysis (d). The sequence is numbered relative to the transcription start site from 5'-RACE results (the bold G nucleotide). The putative translation start site, RBS, -10 region, -35 promoter sequence, and histone-like protein HU binding site (hbs) are underlined. Boxes indicate the putative consensus transcriptional regulator binding regions. (d) Primer extension analysis of pegA. The products of reverse-transcription (lane 1, PEG-4000-grown cells and lane 2, glucose-grown cells) were coelectrophoresed with a DNA-sequencing ladder (A, G, C, and T) of the pCR-PpegA. The expanded views of the nucleotide sequence around the transcription initiation sites (t1 and t2) are shown. [PDF] (75 kb)
