The present invention provides combinatorial methods for rapidly generating a diverse library of glycorandomized structures, comprising incubating one or more aglycons and a pool of NDP-sugars in the presence of a glycosyltransferase. The glycosyltransferase may be one that is associated with or involved in production of natural secondary metabolites, or one which is putatively associated with or involved in production of natural secondary metabolites. The glycosyltransferase may show significant flexibility with respect to its NDP-sugar donors and/or its aglycons. NDP-sugar donors may be commercially available, or may be produced by utilizing mutant or wild type nucleotidyltransferases significant flexibility with respect to their substrates.
本发明提供了快速生成多种糖随机化结构库的组合方法,包括在糖基转移酶存在下培养一种或多种琼脂糖和NDP-糖池。糖基转移酶可以是与天然次生代谢物的生产有关或参与生产的糖基转移酶,也可以是推测与天然次生代谢物的生产有关或参与生产的糖基转移酶。糖基转移酶在其 NDP-糖供体和/或其糖醛酸方面可以表现出很大的灵活性。NDP 糖供体可以从市场上买到,也可以通过利用突变型或野生型核苷酸转移酶对底物的极大灵活性来生产。
