- (3S,4R)-3,4-dihydroxycyclohexa-1,5-diene-1,4-dicarboxylate + NAD+ 3,4-dihydroxybenzoate + CO2 + NADH
Thus, the two substrates of this enzyme are (3S,4R)-3,4-dihydroxycyclohexa-1,5-diene-1,4-dicarboxylate and NAD+, whereas its 3 products are 3,4-dihydroxybenzoate, CO2, and NADH.
This enzyme is a part of the terephthalate degradation pathway in bacteria.[1]
Family
editThis 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 (3S,4R)-3,4-dihydroxycyclohexa-1,5-diene-1,4-dicarboxylate:NAD+ oxidoreductase. Another name in common use is (1R,2S)-dihydroxy-3,5-cyclohexadiene-1,4-dicarboxylate dehydrogenase. This enzyme employs one cofactor, iron.
