Abstract
Substantially pure glycosidases capable for cleaving selected glycosidic bonds have been described including glycosidases isolated from Xanthomonas and recombinant glycosidases. Substrate specificity of isolated enzymes have been identified for GlcNac&bgr;1-X, Gal&agr;1-3R, Gal&agr;1-6R, Gal&bgr;1-3R, Fuc&agr;1-2R, Fuc&agr;1-3R, Fuc&agr;1-4R, Man&agr;1-2R, Man&agr;1-3R, Man&agr;1-6R, Man&bgr;1-4R, Xyl&bgr;1-2R, Glc&bgr;1-4R, and Gal&bgr;1-4R providing improved capability for selectively cleaving a glycosidic linkage in a carbohydrate substrate and for forming modified carbohydrates.
