Putative FnrL binding sites detected by ChIP–chip analysis or by bioinformatic analysis of the <i>R. sphaeroides</i> genome sequence.

1Chromosomes or plasmids. 2Genomic coordinates of regions of the genome that were significantly enriched by chromatin immuno-precipitation using antibodies against FnrL. 3Indicates if genomic regions bound by FnrL overlap with regions bound by σ70 as determined by chromatin immuno-precipitation using antibodies against σ70. 4Genomic coordinates, scores (log-likelihood ratio), and sequences of putative FnrL binding sites identified using the position-weighted matrix constructed from the conserved DNA target sequence of the FNR-type proteins across α-proteobacteria. 5Locus number and annotations of the FnrL target genes. The signs indicates whether the transcription of the target operons is increased (+) or decreased (−) by FnrL binding.
