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

inquiry

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
