L-galactose 1-dehydrogenase (EC 1.1.1.316, L-GalDH, L-galactose dehydrogenase) is an enzyme with systematic name L-galactose:NAD+ 1-oxidoreductase.[1][2][3][4] This enzyme catalyses the following chemical reaction
- L-galactose + NAD+ L-galactono-1,4-lactone + NADH + H+
The enzyme catalyses a step in the ascorbate biosynthesis in higher plants.
