The object of the present invention is to provide annα-isomaltosyl-transferring enzyme which forms ancyclotetrasaccharide having the structure of cyclo{→6)-α-D-glucopyranosyl-(1→3)-α-D-glucopyranosyl-(1→6)-α-D-glucopyranosyl-(1→3)-α-D-glucopyranosyl-(1→}nfrom a saccharidenhaving a glucose polymerization degree of at least three andnhaving both the α-1,6 glucosidic linkage as a linkage at thennon-reducing end and the α-1,4 glucosidic linkage other than thenlinkage at the non-reducing end; microorganisms which producenthe enzyme; process for producing the enzyme; cyclotetrasaccharidenor saccharide compositions comprising the same; andnuses thereof. |
