IUBMB Enzyme Nomenclature


Accepted name: D-glyceraldehyde dehydrogenase (NADP+)

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, glyceraldehyde dehydrogenase (FAD-containing).
