Enzyme Information

1.1.1.120	Galactose 1-dehydrogenase (NADP(+)). based on mapping to UniProt O93715 D-galactose + NADP(+) = D-galactono-1,5-lactone + NADPH. -!- Also acts on L-arabinose, 6-deoxy- and 2-deoxy-D-galactose.
1.1.1.48	D-galactose 1-dehydrogenase. based on mapping to UniProt O93715 D-galactose + NAD(+) = D-galactono-1,4-lactone + NADH. -!- This enzyme is part of the De Ley-Doudoroff pathway, which is used by some bacteria during growth on D-galactose.
1.1.1.359	Aldose 1-dehydrogenase (NAD(P)(+)). based on mapping to UniProt O93715 An aldopyranose + NAD(P)(+) = an aldono-1,5-lactone + NAD(P)H. -!- The enzyme from the archaeon Sulfolobus solfataricus shows broad specificity toward aldoses (D-glucose, D-galactose, D-xylose, L-arabinose, 6-deoxy-D-glucose, D-fucose) and can utilize NAD(+) and NADP(+) with similar catalytic efficiency. -!- It is involved in aldose catabolism via the branched variant of the Entner-Doudoroff pathway.
1.1.1.47	Glucose 1-dehydrogenase (NAD(P)(+)). based on mapping to UniProt O93715 D-glucose + NAD(P)(+) = D-glucono-1,5-lactone + NAD(P)H. -!- This enzyme has similar activity with either NAD(+) or NADP(+). -!- Cf. EC 1.1.1.118 and EC 1.1.1.119.
