Reaction: D-glyceraldehyde + NADP+ + H2O = D-glycerate + NADPH + H+
Other name(s): glyceraldehyde dehydrogenase; GADH
Systematic name: D-glyceraldehyde:NADP+ oxidoreductase
Comments: The enzyme from the archaea Thermoplasma acidophilum and Picrophilus torridus is involved in the non-phosphorylative Entner-Doudoroff pathway. cf. EC 184.108.40.206, glyceraldehyde dehydrogenase (FAD-containing).
