NMR Structure(hide GO term definitions)
Chain A   (DGDG2_ARATH | Q8W1S1)
molecular function
    GO:0035250    UDP-galactosyltransferase activity    Catalysis of the transfer of a galactose group from UDP-galactose to an acceptor molecule.
    GO:0008194    UDP-glycosyltransferase activity    Catalysis of the transfer of a glycosyl group from a UDP-sugar to a small hydrophobic molecule.
    GO:0046481    digalactosyldiacylglycerol synthase activity    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.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
    GO:0016757    transferase activity, transferring glycosyl groups    Catalysis of the transfer of a glycosyl group from one compound (donor) to another (acceptor).
biological process
    GO:0016036    cellular response to phosphate starvation    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of phosphate.
    GO:0009247    glycolipid biosynthetic process    The chemical reactions and pathways resulting in the formation of glycolipid, a class of 1,2-di-O-acylglycerols joined at oxygen 3 by a glycosidic linkage to a carbohydrate part (usually a mono-, di- or tri-saccharide).
cellular component
    GO:0009507    chloroplast    A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.
    GO:0009707    chloroplast outer membrane    The outer, i.e. cytoplasm-facing, lipid bilayer of the chloroplast envelope.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0009536    plastid    Any member of a family of organelles found in the cytoplasm of plants and some protists, which are membrane-bounded and contain DNA. Plant plastids develop from a common type, the proplastid.
    GO:0009527    plastid outer membrane    The outer, i.e. cytoplasm-facing, lipid bilayer of the plastid envelope.
