Cycloisomaltooligosaccharides, an enzyme and process for producing said oligosaccharides, and a process for producing said enzyme

摘要

The present invention relates to a novel cycloisomaltooligosaccharide selected from the group consisting of novel cycloisomaltoheptaose having a cyclic structure composed of 7 glucose residues in α-1,6 linkage, novel cycloisomaltooctaose having a cyclic structure composed of 8 glucose residues in α-1,6 linkage and novel cycloisomaltononaose having a cyclic structure composed of 9 glucose residues in α-1,6 linkage, novel cycloisomaltooligosaccharide synthase forming said oligosaccharides from dextran, and a process for producing said oligosaccharides by use of said enzyme or a microorganism capable of producing said enzyme.
