IUBMB Enzyme Nomenclature


Accepted name: D-arabinose 1-dehydrogenase (NADP+)

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 (D-arabinose 1-dehydrogenase (NAD+)) and EC (D-arabinose 1-dehydrogenase [NAD(P)+]), this enzyme is specific for NADP+.
