CDP-4-dehydro-6-deoxyglucose reductase () is an enzyme that catalyzes the chemical reaction
The 4 substrates of this enzyme are CDP-4-dehydro-3,6-dideoxy-D-glucose, nicotinamide adenine dinucleotide ion, nicotinamide adenine dinucleotide phosphate ion, and water, whereas its 4 products are CDP-4-dehydro-6-deoxy-D-glucose, nicotinamide adenine dinucleotide, nicotinamide adenine dinucleotide phosphate, and hydrogen ion.
This enzyme belongs to the family of oxidoreductases, specifically those acting on CH or CH<sub>2</sub> groups with NAD<sup>+</sup> or NADP<sup>+</sup> as acceptor. The systematic name of this enzyme class is CDP-4-dehydro-3,6-dideoxy-D-glucose:NAD(P)<sup>+</sup> 3-oxidoreductase. Other names in common use include CDP-4-keto-6-deoxyglucose reductase, cytidine diphospho-4-keto-6-deoxy-D-glucose reductase, cytidine diphosphate 4-keto-6-deoxy-D-glucose-3-dehydrogenase, CDP-4-keto-deoxy-glucose reductase, CDP-4-keto-6-deoxy-D-glucose-3-dehydrogenase system, and NAD(P)H:CDP-4-keto-6-deoxy-D-glucose oxidoreductase. This enzyme participates in starch and sucrose metabolism.
