Thus, the two substrates of this enzyme are UDP-galactose and sn-glycerol 3-phosphate, whereas its two products are UDP and 2-(alpha-D-galactosyl)-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 2-alpha-D-galactosyltransferase. Other names in common use include floridoside-phosphate synthase, UDP-galactose:sn-glycerol-3-phosphate-2-D-galactosyl transferase, FPS, UDP-galactose, sn-3-glycerol phosphate:1->2' galactosyltransferase, floridoside phosphate synthetase, and floridoside phosphate synthase.
