Identification of the AmrZ binding site. A. MEME logo identified as the AmrZ binding site. This motif is present in 76% of the enriched regions identified by ChIP-Seq. B. Frequency distribution of the distance of the motif to the peak center. The center of the peak was determined as the nucleotide(s) with the maximum reads within each region. A window of 20 nucleotides was used. More than 90% of the motifs were located within 50 nucleotides from the peak center. C. Alignment of the AmrZ binding site located upstream the amrZ gene in selected pseudomonads’ genomes. The two GC rich regions within the motif are indicated in red and blue. P value for all the motifs with respect to the MEME logo is indicated.
