概要

• 論文の詳細を見る

• A transglycosylation reaction with moranoline (1-deoxynojirimycin) was carried out with α-cyclodextrin as the glucose donor and Bacillus macerans amylase as cyclodextrin glycosyltransferase [EC 2.4.1.19]. The resultant transglycosylation products were hydrolyzed by glucoamylase [EC 3.2.1.3] from Rhizopus niveus. The hydrolyzate (the transglycosylation product of the lowest molecular weight) was isolated and the structure was found by physico-chemical methods to be 4-O-α-D-glucopyranosyl-moranoline.
