Figure 2
Alignment of the conserved putative transcription factor binding sites present in the genomic upstream sequences of five yjaX-coregulated transcriptional units. Nucleotide-specific coloring of the aligned residues was applied for sites with >80% conservation. Underneath, a sequence logo representation displays the information content per aligned site. Note the clear palindromic symmetry of the motif, indicating that a dimeric transcription factor binds to these DNA sites, which implies a role as cis-acting recognition motifs for the regulation of the Bacillus subtilis type II fatty acid biosynthesis pathway.
