dihydrodiol dehydrogenase catalyzes the NADP+-linked oxidation of dihydrodiols of aromatic hydrocarbons to their corresponding catechols and is regarded as a toxication enzyme in the metabolism of carcinogenic polycyclic aromatic hydrocarbons because oxidation by the enzyme yields reactive and redox-active ortho-quinones and reactive oxygen species, broad substrate specificity indicates additional roles of the enzyme in the metabolism of endogenous and xenobiotic carbonyl compounds and the prevention of the development of glycation
