title: p-hydroxylation reactions catalyzed by naphthalene dioxygenase.
abstract: In this study, naphthalene dioxygenase is shown to catalyze the oxidation of methylphenols and chlorophenols by p- and/or o-hydroxylation reactions. For instance, m-cresol was oxidized to methylhydroquinone with formation of 3- and 4-methylcatechol as minor products. 2-Chlorophenol was exclusively oxidized to chlorohydroquinone, which is an important building block for pharmaceutical products and other organic compounds. The oxygen incorporated in the p-hydroxylation reaction from m-cresol is derived from water with consumption of O2.
