CC -!- FUNCTION: Involved in the synthesis of diacylglycerol galactolipids
CC that are specifically found in thylakoid membranes. Specific for alpha-
CC glycosidic linkages (PubMed:10381884, PubMed:14600212). Responsible for
CC the final assembly of galactolipids in photosynthetic membranes.
CC Digalactosyldiacylglycerol (DGDG) provides stability to the photosystem
CC I (PSI) complex, especially to the PsaA, PsaB, PsaC, PsaL and PsaH
CC subunits (PubMed:15961080, PubMed:16854937).

CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 1,2-diacyl-3-O-(beta-D-galactosyl)-sn-glycerol + UDP-alpha-
CC D-galactose = 1,2-diacyl-3-O-[alpha-D-galactosyl-(1->6)-beta-D-
CC galactosyl]-sn-glycerol + H(+) + UDP; Xref=Rhea:RHEA:10520,

CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast outer membrane
CC {ECO:0000269|PubMed:11429410}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q9S7D1-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9S7D1-2; Sequence=VSP_022342;
CC -!- INDUCTION: 6-fold up-regulation by phosphate deficiency.
CC {ECO:0000269|PubMed:14600212}.
CC -!- DISRUPTION PHENOTYPE: Altered thylakoid membrane lipid composition and
CC stunted phenotype. {ECO:0000269|PubMed:10381884}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase group 1 family.
CC Glycosyltransferase 4 subfamily. {ECO:0000305}.
