Vitexin beta-glucosyltransferase (EC 2.4.1.105) is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme characterised from Silene alba are the flavonoid, vitexin, and UDP-glucose. Its products are vitexin 2"-O-β-D-glucoside and uridine diphosphate (UDP). 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.
