In enzymology, a D-arabinose 1-dehydrogenase (EC 1.1.1.116) is an enzyme that catalyzes the chemical reaction
- D-arabinose + NAD+ [math]\displaystyle{ \rightleftharpoons }[/math] D-arabinono-1,4-lactone + NADH + H+
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.
