- UDP-glucose + dolichyl phosphate UDP + dolichyl beta-D-glucosyl phosphate
Thus, the two substrates of this enzyme are UDP-glucose and dolichyl phosphate, whereas its two products are UDP and dolichyl beta-D-glucosyl phosphate.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:dolichyl-phosphate beta-D-glucosyltransferase. Other names in common use include polyprenyl phosphate:UDP-D-glucose glucosyltransferase, UDP-glucose dolichyl-phosphate glucosyltransferase, uridine diphosphoglucose-dolichol glucosyltransferase, UDP-glucose:dolichol phosphate glucosyltransferase, UDP-glucose:dolicholphosphoryl glucosyltransferase, UDP-glucose:dolichyl monophosphate glucosyltransferase, and UDP-glucose:dolichyl phosphate glucosyltransferase. This enzyme participates in n-glycan biosynthesis.
