In enzymology, an isovitexin beta-glucosyltransferase (EC 2.4.1.106) is an enzyme that catalyzes the chemical reaction

UDP-glucose + isovitexin UDP + isovitexin 2"-O-beta-D-glucoside

Thus, the two substrates of this enzyme are UDP-glucose and isovitexin, whereas its two products are UDP and isovitexin 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:isovitexin 2"-O-beta-D-glucosyltransferase. This enzyme is also called uridine diphosphoglucose-isovitexin 2"-glucosyltransferase.
