<p>α-Isomaltosylglucosaccharide synthase capable of transferring a-glucosyl from a saccharide, which carries an α-glucosyl bond as the binding manner at the nonreducing end and has a degree of glucose polymerization of at least 2, without substantially elevating the reducing ability to thereby form a saccharide which carries an α-1,6 glucosyl bond as the binding manner at the nonreducing end and an α-1,4 glucosyl bond as a binding manner at other than the nonreducing end and has a degree of glucose polymerization of at least 3; cyclic tetrasaccharides obtained by using this enzyme; carbohydrates containing the same; and use thereof.</p> |
