In enzymology, a sn-glycerol-3-phosphate 1-galactosyltransferase (EC 2.4.1.96) is an enzyme that catalyzes the chemical reaction
- UDP-galactose + sn-glycerol 3-phosphate [math]\displaystyle{ \rightleftharpoons }[/math] UDP + alpha-D-galactosyl-(1,1')-sn-glycerol 3-phosphate
Thus, the two substrates of this enzyme are UDP-galactose and sn-glycerol 3-phosphate, whereas its two products are UDP and alpha-D-galactosyl-(1,1')-sn-glycerol 3-phosphate.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-galactose:sn-glycerol-3-phosphate 1-alpha-D-galactosyltransferase. Other names in common use include isofloridoside-phosphate synthase, UDP-Gal:sn-glycero-3-phosphoric acid 1-alpha-galactosyl-transferase, UDPgalactose:sn-glycerol-3-phosphate alpha-D-galactosyltransferase, uridine diphosphogalactose-glycerol phosphate galactosyltransferase, and glycerol 3-phosphate 1alpha-galactosyltransferase.
