D-arabinitol dehydrogenase (NADP+)

D-arabinitol dehydrogenase (NADP) (EC 1.1.1.287, NADP-dependent D-arabitol dehydrogenase, ARD1p, D-arabitol dehydrogenase 1) is an enzyme with systematic name D-arabinitol:NADP oxidoreductase. This enzyme catalyses the following chemical reaction

(1) D-arabinitol + NADP

\rightleftharpoons

D-xylulose + NADPH + H

(2) D-arabinitol + NADP

\rightleftharpoons

D-ribulose + NADPH + H

The enzyme present in the fungus Uromyces fabae can make use D-arabinitol and D-mannitol in the forward direction, and D-xylulose, D-ribulose and D-fructose in the reverse direction.
