Process for producing carbohydrate or glycoconjugate

摘要

To provide a process for producing a carbohydrate or a glycoconjugate without forming any hydrolytic product of the remodeled sugar chain. A process for producing a carbohydrate or a glycoconjugate by a remodeling reaction in the presence of a glycosidase which performs the remodeling reaction in an aqueous medium containing a water-soluble ketone and/or dioxane. Examples of the glycosidase include endoglycosidases such as Endo-A. Examples of the ketone include acetone.
