Genomic organization and regulatory sites in upstream regions of siderophore genes.

<p>A: Representation of siderophore biosynthesis and uptake genes localization in <i>Pb</i>01, <i>Pb</i>18 and <i>Pb</i>03 genomes. B: Schematic figure showing the position and sequence of putative regulatory sites in upstream regions of siderophore genes in <i>Pb</i>01. A black line represents nucleotides (nt) located 5′ to the open reading frame of each gene: <i>sidD</i> 679 nt, <i>sidF</i> 2409 nt, <i>mirB</i> 3376 nt. The intergenic region between <i>sidI</i> and <i>sidA</i> includes 1005 nt. Numbers represent the number of nucleotides upstream the start codon of each gene where the regulatory sequence was found (vertical line). In case of divergent genes, the nucleotide position is relative to <i>sidA</i>. H: A/T/C; R: A/G; W: A/T.
