D arabinose 1 dehydrogenase

In enzymology, a D-arabinose 1-dehydrogenase (EC 1.1.1.116) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are D-arabinose and NAD⁺, whereas its 3 products are D-arabinono-1,4-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-arabinose:NAD⁺ 1-oxidoreductase. Other names in common use include NAD⁺-pentose-dehydrogenase, and arabinose(fucose)dehydrogenase.
