From: Architecture of divergent flagellar promoters controlled by CtrA in Rhodobacter sphaeroides
Transcriptional start sites of the flgE2, fliF2, flgB2, fliL2 and fliI2 promoters The transcriptional start site (+ 1), is indicated by a bent arrow and the nucleotide is shaded in pink. The conserved nucleotides A and G at − 11 and − 4 positions, respectively are shaded in blue. The nucleotides matching with the consensus CtrA-binding site are highlighted in yellow. The translation codons for FlgE2, FliF2, FlgB2, FliL2 and FliI2, are underlined
