Enzymatic synthesis of kojioligosaccharides using kojibiose phosphorylase.

We have attempted to synthesize kojioligosaccharides (oligosaccharides having the alpha-1,2 glycosidic linkage at the nonreducing end) using two methods. In the first, mixtures of various proportions of glucose and beta-D-glucose-1-phosphate (beta-G1P) were allowed to react in the presence of kojibiose phosphorylase (KPase). In the second, maltose was allowed to react with KPase and maltose phosphorylase (MPase) simultaneously. In the former method, kojioligosaccharides having only the alpha-1,2 glucosidic linkage were synthesized and the average degree of polymerization (D.P.) of oligosaccharides increased with decreasing proportions of glucose. In the second method, kojioligosaccharides were obtained at approximately 70% yields under optimum conditions. 4-alpha-D-Kojibiosyl-glucose, kojitriose and kojitetraose, the principal kojioligosaccharides synthesized, were not hydrolyzed by salivary amylase, artificial gastric juice, pancreatic amylase, or small intestinal enzymes. << Less
