Operons associated with a FNR ChIP-seq peak and lacking a FNR-dependent change in expression in GMM but are repressed by Fur (Category 4).

aGenomic location within each FNR ChIP-seq peak with the highest read count (the summit of the peak).bFirst gene of the operon downstream of the FNR ChIP-seq peak, and operon designation was obtained from EcoCyc [70]. For peaks located within divergent promoters with both operons repressed by Fur, both genes are identified, separated by “/”.cIdentification number (B-number) for the first gene in each operon, obtained from EcoCyc [70]. For peaks located within divergent promoters with both operons repressed by Fur, both B-numbers are identified, separated by “/”.dFunctional description of the products of the operons, obtained from EcoCyc [70]. For peaks located within divergent promoters with operons repressed by Fur, the functions of both operons are listed, separated by “/”.eReference for Fur repression of each operon.
