Alignment of the pheBA and catBC promoter regions revealed the presence of two highly homologous CatR binding sites in these promoters. The functionality of the CatR binding site in pheBA promoter was confirmed by promoter deletion analysis. Comparison of pheBA expression levels in wild type and catR mutant strains suggested that CatR acted as a transcriptional activator.
Regulated genes for each binding site are displayed below. Gene regulation diagrams show binding sites, positively-regulated genes, negatively-regulated genes, both positively and negatively regulated genes, genes with unspecified type of regulation. For each indvidual site, experimental techniques used to determine the site are also given.
