摘要： The present invention has objects to provide a novel cyclic saccharide composed of D-glucose as constituents, a novel enzyme forming the cyclic saccharide, processes for producing the same, and uses thereof. The present invention solves the above objects by providing cycloisomaltotetraose having a structure in which four D-glucose molecules are bound in cyclic form via α-1,6 glucosidic linkages, a cycloisomaltotetraose-forming enzyme, a DNA encoding the enzyme, processes for producing the same, and uses thereof.
