- 7,8-dihydro-7,8-dihydroxykynurenate + NAD+ 7,8-dihydroxykynurenate + NADH + H+
Thus, the two substrates of this enzyme are 7,8-dihydro-7,8-dihydroxykynurenate and NAD+, whereas its 3 products are 7,8-dihydroxykynurenate, 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 7,8-dihydro-7,8-dihydroxykynurenate:NAD+ oxidoreductase. Other names in common use include 7,8-dihydro-7,8-dihydroxykynurenate dehydrogenase, and 7,8-dihydroxykynurenic acid 7,8-diol dehydrogenase. This enzyme participates in tryptophan metabolism.
