In enzymology, quinate dehydrogenase (EC 1.1.1.24) is an enzyme that catalyzes the chemical reaction
- REDIRECT Template:Chemical reaction
The two substrates of the enzyme are L-quinic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 3-dehydroquinic acid, reduced NADH, and a proton.[1][2][3]
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.
