Vitexin beta-glucosyltransferase

From Wikipedia, the free encyclopedia

In enzymology, a vitexin beta-glucosyltransferase (EC 2.4.1.105) is an enzyme that catalyzes the chemical reaction

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.
