Patent ID: 7094563

Claim:
A method for cleaving a glycosidic bond in a carbohydrate, comprising the steps of: (a) adding to the carbohydrate, a glycosidase of defined substrate specificity obtainable from a Xanthomonas species wherein the glycosidase is selected from a β1-3>>4 galactosidase, an α1-2,3 mannosidase, a β-glucosidase, an α1-3,4 fucosidase, an α1-2 fucosidase, a β-N-acetylglucosaminidase, β-N-Acetylglucosaminidase, an α1-6 mannosidase, an α1-3,6 galactosidase, an α1-3,6 mannosidase, a β-xylosidase and a β-mannosidase; and (b) cleaving the glycosidic bond between constituent monosaccharides of the carbohydrate by means of the glycosidase.
