Term Name:	digalactosyldiacylglycerol synthase activity
Synonyms:	DGD1, DGD2, DGDG synthase activity, UDP-galactose-dependent DGDG synthase activity, UDP-galactose-dependent digalactosyldiacylglycerol synthase activity, UDP-galactose:3-(beta-D-galactosyl)-1,2-diacyl-sn-glycerol 6-alpha-galactosyltransferase activity, UDP-galactose:MGDG galactosyltransferase activity
Definition:	Catalysis of the reaction: 1,2-diacyl-3-beta-D-galactosyl-sn-glycerol + UDP-D-galactose = 3-[alpha-D-galactosyl-(1->6)-beta-D-galactosyl]-1,2-diacyl-sn-glycerol + H+ + UDP.
