- UDP-glucose + vitexin UDP + vitexin 2"-O-beta-D-glucoside
Thus, the two substrates of this enzyme are UDP-glucose and vitexin, whereas its two products are UDP and vitexin 2"-O-beta-D-glucoside.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:vitexin 2. This enzyme is also called uridine diphosphoglucose-vitexin 2"-glucosyltransferase.
