In enzymology, a (3S,4R)-3,4-dihydroxycyclohexa-1,5-diene-1,4-dicarboxylate dehydrogenase (EC 1.3.1.53) is an enzyme that catalyzes the chemical reaction

(3S,4R)-3,4-dihydroxycyclohexa-1,5-diene-1,4-dicarboxylate + NAD⁺${\displaystyle \rightleftharpoons }$ 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

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 (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.
