The naphthalene catabolic genes are located in most cases on plasmids. In this group the best-studied plasmid is NAH7 of P. putida PpG7. It carries two operons, one of which enables the utilization of naphthalene and the other salicylate. Both operons are turned on by the product of another NAH7 gene, nahR, in the presence...

Figure 4, Construction of plasmids harboring mobile expression elements containing structural genes for the conversion of toluene to p-cresol, and p-cresol to HBA. (a) pESMll and (b) pESM23. The structure of the mini-TnS transposons is emphasized in the figure for clarity. The DNA sequences coding antibiotic resistance markers aphA and tet, regulatory proteins lacfi and nahR, and promoters Ptrc and Psal are indicated. The mobile units are present in the delivery plasmid pUT as XbaTEcoRI restriction fragments (44).
