ID   2.4.1.46
DE   monogalactosyldiacylglycerol synthase.
AN   1,2-diacylglycerol 3-beta-galactosyltransferase.
AN   1beta-MGDG.
AN   MGDG synthase.
AN   UDPgalactose:1,2-diacylglycerol 3-beta-D-galactosyltransferase.
AN   UDP-galactose:diacylglycerol galactosyltransferase.
AN   UDP galactose-1,2-diacylglycerol galactosyltransferase.
AN   UDP-galactose-diacylglyceride galactosyltransferase.
AN   uridine diphosphogalactose-1,2-diacylglycerol galactosyltransferase.
CA   a 1,2-diacyl-sn-glycerol + UDP-alpha-D-galactose = a 1,2-diacyl-3-
CA   O-(beta-D-galactosyl)-sn-glycerol + H(+) + UDP.
CC   -!- This enzyme adds only one galactosyl group to the diacylglycerol;
CC       EC 2.4.1.241 adds a galactosyl group to the product of the above
CC       reaction.
CC   -!- There are three isoforms in Arabidopsis that can be divided into two
CC       types, A-type (MGD1) and B-type (MGD2 and MGD3).
CC   -!- MGD1 is the isoform responsible for the bulk of
CC       monogalactosyldiacylglycerol (MGDG) synthesis in Arabidopsis.
