Cis-3,4-dihydrophenanthrene-3,4-diol dehydrogenase

Template:Short description Template:Infobox enzyme In enzymology, a cis-3,4-dihydrophenanthrene-3,4-diol dehydrogenase (Template:EC number) is an enzyme that catalyzes the chemical reaction

(+)-cis-3,4-dihydrophenanthrene-3,4-diol + NAD⁺

⇌

phenanthrene-3,4-diol + NADH + H⁺

Thus, the two substrates of this enzyme are (+)-cis-3,4-dihydrophenanthrene-3,4-diol and NAD⁺, whereas its 3 products are phenanthrene-3,4-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-3,4-dihydrophenanthrene-3,4-diol:NAD+ 3,4-oxidoreductase. This enzyme participates in naphthalene and anthracene degradation.
