The formation ofcis-l,2-dihydroxy-l,2,-dihydronaphthalene from naphthalene by naphthalene oxygenase, purified from Corynebacterium renale ATCC 15075, was demonstrated to involve oxidation of a mol NADH and consumption of one mol oxygen. The enzyme contains one g-atom Fe and one FAD. Catalase inhibited product formation and H2O2 could substitute for NADH in the reaction. Superoxide dismutase inh...
