2.4.1.96 |
Accepted name: |
sn-glycerol-3-phosphate 1-galactosyltransferase |
Reaction: |
UDP-α-D-galactose + sn-glycerol 3-phosphate = UDP + 1-O-α-D-galactosyl-sn-glycerol 3-phosphate |
Other name(s): |
isofloridoside-phosphate synthase; UDP-Gal:sn-glycero-3-phosphoric acid 1-α-galactosyl-transferase; UDPgalactose:sn-glycerol-3-phosphate α-D-galactosyltransferase; uridine diphosphogalactose-glycerol phosphate galactosyltransferase; glycerol 3-phosphate 1α-galactosyltransferase; UDP-galactose:sn-glycerol-3-phosphate 1-α-D-galactosyltransferase |
Systematic name: |
UDP-α-D-galactose:sn-glycerol-3-phosphate 1-α-D-galactosyltransferase |
Comments: |
The product is hydrolysed by a phosphatase to isofloridoside, which is involved in osmoregulation (cf. EC 2.4.1.137 sn-glycerol-3-phosphate 2-α-galactosyltransferase). |
