Abstract Previous work suggested that (benR) can substitute for the TOL plasmid-encoded xylS regulatory gene which promotes gene expression from the OP2 region of the lower pathway operon. Accordingly, structural and regulatory gene mutations were distinguished by the ability of benzoate-grown mutant strains to induce expression from OP2 without xylS using the TOL plasmid xylE gene (encoding catechol 2,3-dioxygenase) as reporter. A cloned 12 kb BamHI chromosomal DNA fragment from the P. aeruginosa PA01 chromosome complemented all mutations as shown by restoration of growth on benzoate minimal medium. Southern hybridizations demonstrated that DNA encoding the benzoate dioxygenase structural genes showed homology to DNA encoding toluate dioxygenase from the TOL plasmid pWWO, but benR did not show homology to xylS. Evolutionary relationships between regulatory systems of chromosomal and plasmid encoded genes for catabolism of benzoate and related compounds are suggested.
