In enzymology, a quinate dehydrogenase (EC1.1.1.24) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are L-quinate and NAD, whereas its 3 products are 3-dehydroquinate, NADH, and H.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD or NADP as acceptor. The systematic name of this enzyme class is L-quinate:NAD 3-oxidoreductase. Other names in common use include quinic dehydrogenase, quinate:NAD oxidoreductase, quinate 5-dehydrogenase, and quinate:NAD 5-oxidoreductase. This enzyme participates in phenylalanine, tyrosine and tryptophan biosynthesis.
