In enzymology, a D-threo-aldose 1-dehydrogenase (EC 1.1.1.122) is an enzyme that catalyzes the chemical reaction
- a D-threo-aldose + NAD a D-threo-aldono-1,5-lactone + NADH + H
Thus, the two substrates of this enzyme are D-threo-aldose and NAD, whereas its 3 products are D-threo-aldono-1,5-lactone, 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 D-threo-aldose:NAD 1-oxidoreductase. Other names in common use include L-fucose dehydrogenase, (2S,3R)-aldose dehydrogenase, dehydrogenase, L-fucose, and L-fucose (D-arabinose) dehydrogenase. This enzyme participates in ascorbate and aldarate metabolism.
