IntEnz Enzyme Nomenclature


Accepted name:
glucose/galactose 1-dehydrogenase
Other names:
dual-specific glucose/galactose dehydrogenase
glucose (galactose) dehydrogenase
glucose/galactose dehydrogenase
Systematic name:
D-glucose/D-galactose 1-dehydrogenase (NADPH)




A zinc protein. The enzyme from the archaeon Picrophilus torridus is involved in glucose and galactose catabolism via the nonphosphorylative variant of the Entner-Doudoroff pathway. It shows 20-fold higher activity with NADP+ compared to NAD+. The oxidation of D-glucose and D-galactose is catalysed at a comparable rate (cf. EC, glucose 1-dehydrogenase (NADP+) and EC, galactose 1-dehydrogenase (NADP+)).
