Provided are the use of glycosyltransferases gGT25, gGT13, gGT30, gGT25-1, gGT25-3, gGT25-5, gGT29, gGT29-3, gGT29-4, gGT29-5, gGT29-6, gGT29-7, 3GT1, 3GT2, 3GT3, 3GT4 and derived polypeptides therefrom in the catalyzed glycosylation of terpenoid compounds and the synthesis of new saponins, wherein the glycosyltransferases can specifically and efficiently catalyze tetracyclic triterpenoid compound substrates at positions C-20 and/or C-6 and/or C-3 during hydroxyl glycosylation, and/or transfer the glycosyl from a glycosyl donor to the first glycosyl of the tetracyclic triterpenoid compounds at position C-3, so as to extend the sugar chain. The glycosyltransferases can also be used for constructing man-made synthetic rare ginsenosides and a variety of new ginsenosides and derivatives thereof.
提供了使用糖基转移酶gGT25、gGT13、gGT30、gGT25-1、gGT25-3、gGT25-5、gGT29、gGT29-3、gGT29-4、gGT29-5、gGT29-6、gGT29-7、3GT1、3GT2、3GT3、3GT4及其衍生的多肽在催化萜类化合物的糖基化和合成新皂苷中的用途,其中糖基转移酶可以特异且高效地催化四环三萜类化合物底物在C-20和/或C-6和/或C-3位置的羟基糖基化,和/或将糖基从糖基供体转移至四环三萜类化合物在C-3位置的第一个糖基,从而延长糖链。这些糖基转移酶还可用于构建人工合成的稀有人参皂苷和各种新人参皂苷及其衍生物。
