Detailed genetic maps of upstream regions of selected genes belonging to the DtxR regulon of C. glutamicum. The nucleotide sequences shown indicate the DtxR binding sites (gray boxes) and the identified transcriptional start sites that were mapped with the RACE method (+1). Bold-faced nucleotides display deduced -35 and -10 hexamer sequences of corynebacterial promoter regions. Potential ribosome-binding sites (RBS) in front of the coding regions are underlined; the ATG start codon is double underlined. The cg0527, cg2782 and cg3327 genes are expressed by leaderless transcripts. Previously identified RipA binding sites in front of the cg0445 genes are marked .
