D arabinitol 2 dehydrogenase

In enzymology, a D-arabinitol 2-dehydrogenase (EC 1.1.1.250) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are D-arabinitol and NAD⁺, whereas its 3 products are D-ribulose, 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-arabinitol:NAD⁺ 2-oxidoreductase (D-ribulose-forming). This enzyme is also called D-arabinitol 2-dehydrogenase (ribulose-forming).
