Promoter organization of the Zur regulon members in C. glutamicum ATCC 13032. A schematic presentation of relevant DNA regions from the C. glutamicum ATCC 13032 genome with detected promoters and candidate Zur-binding sites is presented. The 21-bp motifs are shown as grey boxes. A stretch of ten nucleotides (boxed), located upstream of the cg2911 promoter region, revealed similarity to the right half site of the 21-bp motif. The transcription start sites (+1) were mapped by 5' RACE-PCR and are marked in bold letters. Underlined nucleotides show the deduced - 10 and - 35 regions belonging to the corynebacterial promoters. Putative ribosome-binding sites (RBS) are indicated, start codons are underlined. The transcription start site and the - 10 region of cg0043 were deduced from bioinformatic predictions.
