Enzymatic Synthesis of a New Disaccharide, 6-O-α-Glucopyranosyl-2-deoxy-D-glucose, by Transglucosylation of Schizosaccharomyces pombe α-Glucosidase

抄録

A new a-D-glucosyl-2-deoxy-D-glucose was enzymatically synthesized by the transglucosylation of Schizosaccharornyces pombe α-glucosidase under the co-existence of maltose and 2-deoxy-D-glucose. The disaccharide was chromatographically isolated in a semicrystalline powder (hemihydrate). It was concluded that the sugar was 6-O-α-D-glucopyranosyl-2-deoxy-D-glucose ({α}^D₂₂+108°, in water), which was the main product formed in this transglucosylation.
