In enzymology, a 4-hydroxybenzoate 4-O-beta-D-glucosyltransferase (EC 2.4.1.194) is an enzyme that catalyzes the chemical reaction
- UDP-glucose + 4-hydroxybenzoate UDP + 4-(beta-D-glucosyloxy)benzoate
Thus, the two substrates of this enzyme are UDP-glucose and 4-hydroxybenzoate, whereas its two products are UDP and 4-(beta-D-glucosyloxy)benzoate.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:4-hydroxybenzoate 4-O-beta-D-glucosyltransferase. Other names in common use include uridine diphosphoglucose-4-hydroxybenzoate glucosyltransferase, UDP-glucose:4-(beta-D-glucopyranosyloxy)benzoic acid, glucosyltransferase, HBA glucosyltransferase, p-hydroxybenzoate glucosyltransferase, PHB glucosyltransferase, and PHB-O-glucosyltransferase.
