应用
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.
生化/生理作用
β-galactose dehydrogenase catalyzes the oxidation of β-D-galactose to D-galactono-gammalactone.
单位定义
One unit will convert 1.0 μmole of D-galactose to D-galactonate per min at pH 8.6 at 25 °C.
外形
Suspension in 3.2 M (NH4)2SO4, pH approx. 6.0

We have studied the enzymological properties of L-galactose dehydrogenase (l-GalDH), a key enzyme in the biosynthetic pathway of l-ascorbate (AsA) in plants. L-GalDH was purified approximately 560-fold from spinach leaves. The enzyme was a homodimer with a subunit mass of

Yeasts do not possess an endogenous biochemical pathway for the synthesis of vitamin C. However, incubated with l-galactose, L-galactono-1,4-lactone, or L-gulono-1,4-lactone intermediates from the plant or animal pathway leading to l-ascorbic acid, Saccharomyces cerevisiae and Zygosaccharomyces bailii cells accumulate the

The mechanistic implications of the kinetic behaviour of a fusion protein of beta-galactosidase and galactose dehydrogenase have been analysed in view of predictions based on experimentally determined kinetic parameter values for the galactosidase and dehydrogenase activities of the protein. The

The localization of carbohydrate terminals in Kudoa septempunctata ST3-infected muscle of olive flounder (Paralichthys olivaceus) was investigated using lectin histochemistry to determine the types of carbohydrate sugar residues expressed in Kudoa spores. Twenty-one lectins were examined, i.e., N-acetylglucosamine (s-WGA, WGA
