RT peribacteroid membrane of nitrogen-fixing nodules of Soybean and Lotus.";
RL J. Biol. Chem. 279:34624-34630(2004).
CC -!- FUNCTION: Involved in the synthesis of diacylglycerol galactolipids
CC that are specifically found in thylakoid membranes. Specific for alpha-
CC glycosidic linkages. {ECO:0000269|PubMed:15159398}.
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 ChEBI:CHEBI:58223, ChEBI:CHEBI:66914; EC=2.4.1.241;
CC -!- SUBCELLULAR LOCATION: Symbiosome, peribacteroid membrane {ECO:0000305}.
CC Plastid, chloroplast outer membrane {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: High expression in nodules infected cells, and low
CC in nodule and root vascular tissue. {ECO:0000269|PubMed:15159398}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase group 1 family.
CC Glycosyltransferase 4 subfamily. {ECO:0000305}.
