Comparative sequence analysis of regulatory promoters. (A) Promoters and NagR binding regions of the nag promoter region from strains U2 and CJ2. The arrows indicate the start of translation. The putative −35 and −10 motifs and the putative NagR binding motif are underlined. (B) Alignment of the conserved upstream regions controlled by NahR and NagR regulators. (C) The putative promoter region of nagR2 ORF2 in the small cluster of naphthalene degradation genes in strain CJ2. Conserved regions are enclosed in boxes.
