A novel cyclic pentasaccharide (CPS) and a branched cyclic pentasaccharide (6G-CPS) consisting of d-glucopyranose were synthesized with 6-alpha-glucosyltransferase (6GT) and 3-alpha-isomaltosyltransferase (IMT) from Bacillus globisporus N75. The structure of CPS was cyclo-[-->6)-alpha-D-Glcp-(1-->3)-alpha-D-Glcp-(1-->6)-alpha-D-Glcp-(1-->3)-alpha-D-Glcp-(1-->4)-alpha-D-Glcp-(1-->]. The other, 6G-CPS, had the structure cyclo-[-->6)-alpha-D-Glcp-(1-->3)-alpha-D-Glcp-(1-->6)-alpha-D-Glcp-(1-->3)-[alpha-D-Glcp-(1-->6)]-alpha-D-Glcp-(1-->4)-alpha-D-Glcp-(1-->]. The formation of CPS was presumed to occur after the following four successive reactions: a 6-glucosyltransfer reaction with 6GT, a 4-glucosyltransfer reaction with 6GT, a 3-isomaltosyltransfer reaction with IMT, and a cyclization reaction with IMT.
