In enzymology, an undecaprenyl-phosphate galactose phosphotransferase (EC 2.7.8.6) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are UDP-galactose and undecaprenyl phosphate, whereas its two products are UMP and alpha-D-galactosyl-diphosphoundecaprenol.
This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups. The systematic name of this enzyme class is UDP-galactose:undecaprenyl-phosphate galactose phosphotransferase. Other names in common use include poly(isoprenol)-phosphate galactose phosphotransferase, poly(isoprenyl)phosphate galactosephosphatetransferase, and undecaprenyl phosphate galactosyl-1-phosphate transferase.
Galactose, sometimes abbreviated Gal, is a monosaccharide sugar that is about as sweet as glucose, and about 65% as sweet as sucrose. It is an aldohexose and a C-4 epimer of glucose. A galactose molecule linked with a glucose molecule forms a lactose molecule.
A transferase is any one of a class of enzymes that catalyse the transfer of specific functional groups from one molecule to another. They are involved in hundreds of different biochemical pathways throughout biology, and are integral to some of life's most important processes.
Glycosyltransferases are enzymes that establish natural glycosidic linkages. They catalyze the transfer of saccharide moieties from an activated nucleotide sugar to a nucleophilic glycosyl acceptor molecule, the nucleophile of which can be oxygen- carbon-, nitrogen-, or sulfur-based.
