The regulation of naphthalene metabolism in pseudomonads

The activities of three enzymes specifically involved in naphthalene metabolism have been measured in $\text{Pseudomonas}$ NCIB 9816 after induction with salicylate or 2-hydroxybenzyl alcohol. The results indicate that naphthalene oxygenase, 1,2-dihydroxynaphthalene oxygenase and salicylaldehyde dehydrogenase are induced coordinately and it is suggested that all of the enzymes converting naphthalene to salicylate are regulated coordinately.
