Enzyme Galactose dehydrogenase - Galactose mutarotase
Shipping temperature: ambient
Storage temperature: 2-8oC
Formulation: in 3,2 M ammonium sulphate
Physical form: suspension
EC number :
Galactose dehydrogenase: 1.1.1.48
Galactose mutarotase: 5.1.3.3
CAS:
Galactose dehydrogenase: 9028-54-0
Galactose mutarotase: 9031-76-9
Synonyms:
Galactose dehydrogenase: D-galactose 1-dehydrogenase; D-galactose:NAD+ 1-oxidoreductase
Galactose mutarotase: aldose 1-epimerase; aldose 1-epimerase
Source: Escherichia coli
Specific activity:
Galactose dehydrogenase: ~ 200 U/mL at pH 8,6 and 25oC
Galactose mutarotase: 4,1 mg/mL
Specificity:
Interconversion of the α- and β-anomeric forms of D-galactose is catalysed by β-galactose mutarotase (GMR) (1).
(1) α-D-Galactose ↔ β-D-Galactose.
The β-D-Galactose is oxidised by NAD+ to D-galactonic acid in the presence of β-galactose dehydrogenase (GALDH) at pH 7.5 (2).
(2) β-D-Galactose + NAD+ → D-galactonic acid + NADH + H
Unit definition: one unit of galactose dehydrogenase is defined as the amount of enzyme required to produce one µmole of NADH from NAD+ per minute at pH 8,6, at 25°C
Temperature optima: 25°C
pH optima: 8,6
Stability: minimun 1 year at 4°C
