Expected Taxonomic Range:
Naphthalene is the simplest fused polycyclic aromatic hydrocarbon, and is abundant in soils. Several bacterial species are able to grow on naphthalene as the sole cource of carbon and energy [Shamsuzzaman74, Bosch99, Kulakov00].
Naphthalene is catabolized through cis naphthalene dihydrodiol, salicylaldehyde, and salicylate. The latter is converted into either catechol, which is then degraded by either the meta or the ortho cleavage pathways to TCA cycle intermediates [Barnsley76], or to gentisate, which is degraded by a different pathway to TCA cycle intermediates [Fuenmayor98] (see salicylate degradation I and salicylate degradation II, respectively).
Several different models have been proposed for this pathway, due to the difficulty working with the unstable intermediate naphthalene-1,2-diol, which is rapidly and spontaneously oxidized in water to 1,2-naphthoquinone. The pathway presented here reflects the results of a careful analysis performed by Eaton and Chapman [Eaton92].
The genes encoding the enzymes required for the catabolism of naphthalene are often carried on plasmids, such as the NAH plasmids [Zakharian, Connors82, Yen82]. However, some organisms, such as Pseudomonas stutzeri AN10, carry these genes on their chromosome [Bosch99]. Transcription of the genes in this operon is regulated by a salicylate-dependent transcription regulator (such as NahR for the operon located on the NAH plasmid) [You86, Schell86].
