EC 2.4.1.46 Monogalactosyldiacylglycerol synthase. [-]    

Pathway: Galactosyl Diacylglycerol
Reaction: UDP-alpha-D-galactose + 1,2-diacyl-sn-glycerol = Udp + 3-beta-D- galactosyl-1,2-diacyl-sn-glycerol.

Other 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.
Comments: 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.
