| Abstract: | Specific-length maltooligosaccharides, particularly maltohexaose, maltoheptaose, and maltooctaose, were prepared from cyclomaltooligosaccharides (cyclodextrins, CDs) by the preferential cyclodextrin ring-opening reaction of an amylolytic enzyme from Pyrococcus furiosus. The enzyme primarily produces maltohexaose, maltoheptaose, and maltooctaose by hydrolyzing alpha-, beta-, and gamma-CD, respectively. This study aims to develop a high-efficiency synthesis of specific maltooligosaccharides at high-purity. formula: see text] |
