FIG 2.

Fur binds to the promoter region of the catDE operon in vivo under iron-replete conditions. A zoom-in example of Fur binding at the catDE operon site identified by ChIP-seq. Two biological replicates were included as Exp. 1 and Exp. 2 for each condition. A single peak was annotated at this region for both replicates under iron-sufficient conditions. The peak length was 328 bp for Exp. 1 and 355 bp for Exp. 2. No peaks were annotated at this region for either replicate under iron-deficient conditions. S/N denotes the signal-to-noise ratio for peak calling.
