Descripción

General description

Native β1,2-Xylosidase from Xanthomonas species. Catalyzes the hydrolysis of terminal xylose β1,2-linked to the β-mannose of N-linked oligosaccharides. Enzyme requires removal of α1,3-linked mannose. Enzyme requires 5 mM calcium chloride in reaction buffer for full activity.

Note: 1 mU = 1 milliunit.

Physical form

In 25 mM NaCl, 20 mM Tris-HCl, pH 7.5.

Preparation Note

Following initial use, refrigerate (4°C).

Other Notes

One unit is defined as the amount of enzyme that will release 1 nmol of methylumbelliferone from 4-methylumbelliferyl-7-β-D-xyloside per min at 37°C, pH 5.0.
