FIG. 5.

Multiple alignment of FlgR of C. jejuni (FlgRCj) with homologous transcriptional regulators: FlgR of H. pylori (FlgRHp), FlbD of C. crescentus (FlbDCc), FleR and FleQ of P. aeruginosa (FleQPa and FleRPa), and NtrC of E. coli (NtrCEc). Conserved residues (CON) are indicated wherever four or more sequences have the same residue. A, B, and C indicate the conserved aspartic acid residues corresponding to positions 11, 12, and 54, respectively. D corresponds to the conserved lysine residue at position 104. I and II are the two ATP binding domains, and III indicates the helix-turn-helix DNA binding motif.
