Hydroquinone glucosyltransferase (EC 2.4.1.218) is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme characterised from Rauvolfia are hydroquinone and UDP-glucose. Its products are arbutin 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:hydroquinone-O-beta-D-glucosyltransferase. Other names in common use include arbutin synthase, and hydroquinone:O-glucosyltransferase.
