In enzymology, an UDP-galactose—UDP-N-acetylglucosamine galactose phosphotransferase (EC 2.7.8.18) is an enzyme that catalyzes the chemical reaction
- UDP-galactose + UDP-N-acetyl-D-glucosamine [math]\displaystyle{ \rightleftharpoons }[/math] UMP + UDP-N-acetyl-6-(D-galactose-1-phospho)-D-glucosamine
Thus, the two substrates of this enzyme are UDP-galactose and UDP-N-acetyl-D-glucosamine, whereas its two products are UMP and UDP-N-acetyl-6-(D-galactose-1-phospho)-D-glucosamine.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups transferases for other substituted phosphate groups. The systematic name of this enzyme class is UDP-galactose:UDP-N-acetyl-D-glucosamine galactose phosphotransferase. Other names in common use include uridine diphosphogalactose-uridine diphosphoacetylglucosamine galactose-1-phosphotransferase, galactose-1-phosphotransferase, and galactosyl phosphotransferase.
