In enzymology, a trans-zeatin O-beta-D-glucosyltransferase (EC 2.4.1.203) is an enzyme that catalyzes the chemical reaction
- UDP-glucose + trans-zeatin UDP + O-beta-D-glucosyl-trans-zeatin
Thus, the two substrates of this enzyme are UDP-glucose and trans-zeatin, whereas its two products are UDP and O-beta-D-glucosyl-trans-zeatin.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:trans-zeatin O-beta-D-glucosyltransferase. Other names in common use include zeatin O-beta-D-glucosyltransferase, uridine diphosphoglucose-zeatin O-glucosyltransferase, and zeatin O-glucosyltransferase.
