The organization of naphthalene degradation genes in Pseudomonas putida strain AK5.

The Pseudomonas putida АК5 that was isolated from the slime pit of a Nizhnekamsk oil chemical factory can metabolize naphthalene via salicylate and gentisate. Catabolic genes are localized on non-conjugative IncP-7 plasmid pAK5 of about 115 kb in size. The "classical"nah-1 operon and the novel sgp-operon (salicylate-gentisate pathway) are both involved in naphthalene degradation by P.
