Cis-1,2-dihydro-1,2-dihydroxynaphthalene dehydrogenase

In enzymology, a cis-1,2-dihydro-1,2-dihydroxynaphthalene dehydrogenase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are cis-1,2-dihydronaphthalene-1,2-diol and NAD+, whereas its 3 products are naphthalene-1,2-diol, NADH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is cis-1,2-dihydronaphthalene-1,2-diol:NAD+ 1,2-oxidoreductase. Other names in common use include (+)-cis-naphthalene dihydrodiol dehydrogenase, naphthalene dihydrodiol dehydrogenase, and cis-dihydrodiol naphthalene dehydrogenase. This enzyme participates in 1- and 2-methylnaphthalene degradation and naphthalene and anthracene degradation.
