Transfer Reaction of β-D-Glycofuranose by β-Glycosidase

Transfer reaction of β-D-glucofuranose from phenyl β-D-glucofuranoside to methanol by almond emulsin was recognized. Extent of glucofuranosyl transfer from different aryl β-D-glucofuranoside to alcohol was determined. Influence of pH on the glucofuranosyl transfer was examined. The course of the transfer reaction was also reported. Enzymic transfer of β-D-galactofuranose and β-D-glucofuranosiduronic acid was also investigated. In view of the above facts, it was concluded that β-D-glycofuranosyl residue was transferred by β-glycosidase from phenol to alcohol and conversion of furanose ring to pyranose ring was not occured in the course of enzymic transfer reaction.
