ENZYME entry: EC 2.4.1.46

Accepted Name
Monogalactosyldiacylglycerol synthase.
Alternative Name(s)
1,2-diacylglycerol 3-beta-galactosyltransferase.
1-beta-MGDG.
MGDG synthase.
UDP galactose-1,2-diacylglycerol galactosyltransferase.
UDP-galactose-diacylglyceride galactosyltransferase.
UDP-galactose:diacylglycerol galactosyltransferase.
UDPgalactose:1,2-diacylglycerol 3-beta-D-galactosyltransferase.
Uridine diphosphogalactose-1,2-diacylglycerol galactosyltransferase.
Reaction catalysed
UDP-alpha-D-galactose + 1,2-diacyl-sn-glycerol <=> UDP + 3-beta-D-galactosyl-1,2-diacyl-sn-glycerol
Comment(s)
  • This enzyme adds only one galactosyl group to the diacylglycerol; EC 2.4.1.241 adds a galactosyl group to the product of the above reaction.
  • There are three isoforms in Arabidopsis that can be divided into two types, A-type (MGD1) and B-type (MGD2 and MGD3).
  • MGD1 is the isoform responsible for the bulk of monogalactosyldiacylglycerol (MGDG) synthesis in Arabidopsis.
