β-1, 4-Linked mannooligosaccharides were obtained regioselectively when mannose was incubated with β-mannosidase from Rhizopus niveus. By use of the obtained β-1, 4-linked mannobiose as a donor, the transglycosylation reaction was done with the same enzyme, and β-linked alkyl glycosides were obtained from various alcohols. In the reaction using the β-1, 4-linked mannobiose as a donor and acceptor, β-l, 4-linked mannooligosaccharides were obtained by a transglycosylation mechanism.
当甘露糖与来自Rhizopus niveus的β-甘露糖苷酶一起培养时,β-1,4-连接的甘露寡糖被区域选择性获得。通过使用获得的β-1,4-连接的甘露糖作为供体,与相同的酶进行转糖基化反应,并从各种醇中获得β-连接的烷基糖苷。在以β-1,4-连接的甘露糖作为供体和受体的反应中,通过转糖基化机制获得了β-1,4-连接的甘露寡糖。
