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