a
Operon showing a statistically significant FNR-dependent change in expression compared to WT but lacking a FNR ChIP-seq peak upstream. Operon definitions obtained from EcoCyc [70].
b
Identification number (B-number) for the first gene in each operon, obtained from EcoCyc [70].
c
Cellular function of the product of the operon, obtained from EcoCyc [70].
d
FNR regulation of each operon as identified in the transcriptomic experiments performed in this study.
