Nucleotide analysis of two high-score target regions. A) Promoter sequence of ntcB (all0602), including the NtcA binding site, the -10 box and the TSP (or TSS) (already described) [30], and the midpoint of the target region found in the ChIP-Seq experiment (circled G). B) Analysis of the sequence of the target region found inside ORF alr2482 (midpoint of the target region represented by the circled C), which includes a putative NtcA binding site separated 22 nucleotides from a putative -10 box of an internal regulated TSP [14]. Transcriptomic data was obtained from [13] (12 h after N withdrawal).
