β(1-3) Galactosidase from Xanthomonas manihotis, Recombinant


Cat No.
NATE-1261
Description
β-galactosidase is a hydrolase enzyme that catalyzes the hydrolysis of β-galactosides into monosaccharides. Substrates of different β-galactosidases include ganglioside GM1, lactosylceramides, lactose, and various glycoproteins.
Abbr
GLB, Recombinant (Xanthomonas manihotis)
Alias
β-gal
Source
E. coli
Species
Xanthomonas manihotis
Form
50 mM NaCl, 20 mM Tris-HCl (pH 7.5 25°C) and 0.1 mM Na2EDTA.
Activity
17,000 units/mg
Molecular Weight
66 kDa
Concentration
10,000 units/ml
Specificity
The GlcNAc(β1-6) residue is the only anomeric configuration that can effect the specificity of the enzyme enabling cleavage of the non-reducing β1-4Galactose.
Unit Definition
One unit is defined as the amount of enzyme required to cleave > 95% of the terminal β-D-galactose from 1 nmol of Galβ1-3GlcNAcβ1-3Galβ1-4Glc-7-amino-4-methyl-coumarin (AMC), in 1 hour at 37°C in a total reaction volume of 10 µl.
Storage
at -20°C
