Galactose Oxidase from Dactylium dendroides;D-Galactose:oxygen 6-oxidoreductase CAS:9028-79-9

CAS No.: 9028-79-9
Item No.: E0140
Store at: -20℃

English name:Galactose Oxidase from Dactylium dendroides;D-Galactose:oxygen 6-oxidoreductase

Grade:High purity grade
Molecular weight:68KD
Vitality:≥30units/mg protein

Vitality definition:one unit equals a change in absorbance at 425nm of 1.0 per minute at 25℃,pH6.0 using a perosidase/o-tolidine coupled assay with galactose as the substrate
Optimum pH:7.0

Product description:Supplied as a purified powder,containing sodium phosphate and cucrose as stablilizer.Oxdizes galactose and some galactose derivatives in both free and polymeric forms.Oxidation at the C6 position.
Physicochemical properties: powder. It is an enzyme with copper atom as the active center, which is composed of a single polypeptide chain containing 639 amino acid groups.A kind of non blue oxidase, which contains copper and does not show blue.Unlike blue copper oxidase, its absorption coefficient is very small near 600 nm, which can be monitored by electron spin resonance (ESR) spectrum. Its spectral characteristics are similar to those of inorganic copper coordination compounds.

Purpose: Biochemical research.Catalytic oxidation of galactose to determine the content of galactose in the sample.
