EC Galactolipid galactosyltransferase. [-]    

Pathway: Galactosyl Diacylglycerol
Reaction: 2 3-(beta-D-galactosyl)-1,2-diacyl-sn-glycerol = 3-(alpha-D-galactosyl- (1->6)-beta-D-galactosyl)-1,2-diacyl-sn-glycerol + 1,2-diacyl- sn-glycerol.

2 × 3-(beta-D-galactosyl)-1,2-diacyl-sn-glycerol
= 3-(alpha-D-galactosyl- (1->6)-beta-D-galactosyl)-1,2-diacyl-sn-glycerol
1,2-diacyl- sn-glycerol

Other name(s): Dgdg synthase. Digalactosyldiacylglycerol synthase. Galactolipid-galactolipid galactosyltransferase. Galactolipid:galactolipid galactosyltransferase. Gggt. Interlipid galactosyltransferase.
Comments: By further transfers of galactosyl residues to the digalactosyldiacylglycerol, trigalactosyldiacylglycerol and tetragalactosyldiacylglycerol are also formed. Was originally thought to be the major enzyme involved in the production of digalactosyldiacylglycerol in plants as it masked the effect of the true enzyme (EC Its activity is localized to chloroplast envelope membranes, but it does not contribute to net galactolipid synthesis in plants.
