Amino acid sequence comparison of σ54-dependent regulators involved in aromatic compound catabolism. Domain structure of EtpR: XylR-N, activator of aromatic catabolism (IPR010523); V4R, 4-vinyl reductase (IPR004096); RNA-polymerase/σ54-interaction domain (IPR002078); AAA+ ATPase domain (IPR003593); DNA-binding HTH domain, Fis-type (IPR002197) (a). Schematic enlargement of the regulatory domain (bold grey line) displaying the positions of amino acid residues conserved/similar among the six compared regulatory proteins. b Sequence alignment of the effector specifying region (ESR) in the V4R domain of: Pseudomonas sp. DmpR (YP_009074430), PhlR (YP_009074867) and XylR (YP_009074187); T. aromatica K172 DmpR (CAC12684); "A. aromaticum" EbN1 PdeR (CAI07889) and EtpR (CAI06292) (c). The full-length alignment of the regulatory domain sequences is provided in the Additional file 1: Figure S5
