Method for preparing the disaccharide [α-D-Glep(1→3)]-α-L-Rhap-YR wherein Y is selected from -O- and -S- and R is selected from the group consisting of: C1-C6 alkyl, C1-C6 alkenyl, aryl, allyl, -CO-alkyl (C1-C6), -CO-alkenyl (C1-C6), -CO-aryl, comprising the step of using a mutant of a wild type glycoside hydrolase.
一种制备二糖[α-D-Glep(1→3)]-α-L-Rhap-YR的方法,其中Y选择自-O-和-S-,R选择自以下组:C1-C6烷基,C1-C6烯基,芳基,烯丙基,-CO-烷基(C1-C6),-CO-烯基(C1-C6),-CO-芳基,包括使用野生型糖苷
