Figure 1. ChIP-seq and ChIP-chip data used in this study.

The tracks are (from top): FNR ChIP-seq −O₂ (blue) with peaks upstream of a subset of genes labeled, FNR ChIP-chip in Δhns/ΔstpA −O₂ (black), σ⁷⁰ subunit of RNAP ChIP-seq −O₂ (green), σ⁷⁰ subunit of RNAP ChIP-seq +O₂ (red), H-NS CHIP-chip +O₂ (light purple), H-NS ChIP-chip −O₂ (orange), IHF ChIP-chip −O₂ (purple), Fis ChIP-seq +O₂ [30] (aqua), β subunit of RNAP −O₂ (yellow), β subunit of RNAP +O₂ (dark purple), and genomic coordinates. Locations of FNR binding sites are also shown: predicted FNR binding sites (red lines), FNR ChIP-seq peaks (black lines), FNR peaks upstream of operons showing a FNR-dependent change in expression (blue lines), FNR peaks co-activated by NarL/NarP (green lines), FNR peaks co-activated by CRP (purple lines), and FNR peaks repressed by Fur (yellow lines).
