Enzyme Activity: Dehydrogenase
EC Number: 1.1.1.48
CAS Number: 9028-54-0
Synonyms: D-galactose 1-dehydrogenase; D-galactose:NAD+ 1-oxidoreductase
Source: Prokaryote
Molecular Weight: 36,659
Concentration: Supplied at ~ 100 U/mL
Expression: Recombinant from a Soil prokaryote
Specificity: Catalyses the reaction:
D-galactose + NAD+ = D-galactono-1,4-lactone + NADH + H
Also acts on L-arabinose but more slowly.
Specific Activity: ~ 280 U/mg (25oC, pH 8.6 on D-galactose)
Unit Definition: One unit of galactose dehydrogenase activity is defined as the amount of enzyme required to convert one µmole of D-galactose to D-galactanate per minute in the presence of NAD+ in Tris-HCl buffer (93 mM), pH 8.6 at 25oC.
Temperature Optima: 40oC
pH Optima: 8.6
Application examples: Applications for the measurement of D-galactose (and L-arabinose) in carbohydrate research and in the food, fermentation, wine, beverage and dairy industries.

High purity recombinant Galactose dehydrogenase (soil prokaryote) for use in research, biochemical enzyme assays and in vitro diagnostic analysis.
