Naphthalene-degradation upper pathway. The upper pathway is composed of NahAaAbAcAd (naphthalene dioxygenase complex; NDO), cis-naphthalene dihydrodiol dehydrogenase (NahB), 1,2-dihydroxynaphthalene dioxygenase (NahC), 2-hydroxy-2H-chromene-2-carboxylate isomerase (NahD), trans-o-hydroxybenzyl­idenepyruvic hydratase-aldolase (NahE) and salicylaldehyde dehydrogenase (NahF). The main substrates and products for these enzymes are also depicted. (1) Naphthalene, (2) cis-1,2-dihydroxy-1,2-dihydronaphthalene, (3) 1,2-dihydroxy­naphthalene, (4) 2-hydroxy-2H-chromene-2-carboxylic acid, (5) trans-o-hydroxybenzylidenepyruvic acid, (6) salicylaldehyde, (7) pyruvate and (8) salicylic acid (adapted from Peng et al., 2008BB25).
