CatR regulation of the pheBA operon in Pseudomonas putida was investigated as it related to an internal binding site (IBS), identified by DNase I protection in an earlier publication. Deletion analysis and site-directed mutagenesis demonstrated reduced pheBA expression so long as both the recognition binding site (RBS) and activation binding site (ABS) were intact.
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.
