Figure 4From: ChIP analysis unravels an exceptionally wide distribution of DNA binding sites for the NtcA transcription factor in a heterocyst-forming cyanobacteriumConsensus NtcA-binding site. A) Consensus NtcA-sequence derived from the 40 target regions with highest NLQ (Table 2). B) Consensus binding site found using all the putative NtcA binding sequences in Additional file 2: Table S1 (508 sequences). C) Extended consensus NtcA binding site (135 sequences).
