Trans-cinnamate 2-monooxygenase

Trans-1,2-dihydrobenzene-1,2-diol dehydrogenase

In enzymology, a trans-1,2-dihydrobenzene-1,2-diol dehydrogenase is an enzyme that catalyzes the chemical reaction

trans-1,2-dihydrobenzene-1,2-diol + NADP+ rightleftharpoons catechol + NADPH + H+

Thus, the two substrates of this enzyme are trans-1,2-dihydrobenzene-1,2-diol and NADP+, whereas its 3 products are catechol, NADPH, 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 trans-1,2-dihydrobenzene-1,2-diol:NADP+ oxidoreductase. This enzyme is also called dihydrodiol dehydrogenase. This enzyme participates in metabolism of xenobiotics by cytochrome p450.
