Reaction: D-arabinofuranose + NADP+ = D-arabinono-1,4-lactone + NADPH + H+
Other name(s): AraDH; adh-4 (gene name)
Systematic name: D-arabinose:NADP+ 1-oxidoreductase
Comments: The enzyme from the archaeon Saccharolobus solfataricus is tetrameric and contains zinc. L-fucose also is a substrate. In contrast to EC 1.1.1.116 (D-arabinose 1-dehydrogenase (NAD+)) and EC 1.1.1.117 (D-arabinose 1-dehydrogenase [NAD(P)+]), this enzyme is specific for NADP+.
