A highly selective 2''--glycosyltransferase from and biosynthesis of isovitexin 2''--glucoside.

A novel and efficient 2''--glycosyltransferase ZjOGT38 was identified from . It could regio-selectively glycosylate 2-hydroxyflavanone -glycosides. ZjOGT38 allowed biosynthesis of isovitexin 2''--glucoside in .
