Application

β-Galactose Dehydrogenase from Pseudomonas fluorescens has been used for competitive inhibition in lectin histochemistry. It has also been used to measure the hydrolysis activity of Haloferax alicantei β-galactosidase on different disaccharides.

Biochem/physiol Actions

β-galactose dehydrogenase catalyzes the oxidation of β-D-galactose to D-galactono-gammalactone.

Physical form

Suspension in 3.2 M (NH4)2SO4, pH approx. 6.0

Other Notes

One unit will convert 1.0 μmole of D-galactose to D-galactonate per min at pH 8.6 at 25 °C.

Storage Class

Protein molecular modelling and ligand docking were employed for the design of anthraquinone galactosyl-biomimetic dye ligands (galactosyl-mimodyes) for the target enzyme galactose dehydrogenase (GaDH). Using appropriate modelling methodology, a GaDH model was build based on a glucose-fructose oxidoreductase (GFO) protein
