Metabolism of toluene and xylenes by Pseudomonas (putida (arvilla) mt-2: evidence for a new function of the TOL plasmid.


Pseudomonas putida (arvilla) mt-2 carries genes for the catabolism of toluene, m-xylene, and p-xylene on a transmissible plasmid, TOL. These compounds are degraded by oxidation of one of the methyl substituents via the corresponding alcohols and aldehydes to benzoate and m- and p-toluates, respectively, which are then further metabolised by the meta pathway, also coded for by the TOL plasmid. The specificities of the benzyl alcohol dehydrogenase and the benzaldehyde dehydrogenase for their three respective substrates are independent of the carbon source used for growth, suggesting that a single set of nonspecific enzymes is responsible for the dissimilation of the breakdown products of toluene and m- and p-xylene. Benzyl alcohol dehydrogenase and benzaldehyde dehydrogenase are coincidently and possible coordinately induced by toluene and the xylenes, and by the corresponding alcohols and aldehydes. They are not induced in cells grown on m-toluate but catechol 2,3-oxygenase can be induced by m-xylene.
