a Number of operons in σ54-dependent sigmulon, one-component EBP regulome and two-component EBP regulome. Dark grey areas correspond to operons co-regulated by both EBP and σ54 protein. Light grey areas correspond to either operons with EBP binding sites or σ54-dependent promoters only. b Distribution of distances between σ54-dependent promoter and closest EBP binding site
