Chain A,B   (UGPA2_ARATH | Q9M9P3)
molecular function
    GO:0003983    UTP:glucose-1-phosphate uridylyltransferase activity    Catalysis of the reaction: alpha-D-glucose 1-phosphate + UTP = diphosphate + UDP-D-glucose.
    GO:0016779    nucleotidyltransferase activity    Catalysis of the transfer of a nucleotidyl group to a reactant.
    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:0070569    uridylyltransferase activity    Catalysis of the transfer of an uridylyl group to an acceptor.
biological process
    GO:0006011    UDP-glucose metabolic process    The chemical reactions and pathways involving UDP-glucose, uridinediphosphoglucose, a substance composed of glucose in glycosidic linkage with uridine diphosphate.
    GO:0052543    callose deposition in cell wall    Any process in which callose is transported to, and/or maintained in, the cell wall. Callose is a linear 1,3-beta-d-glucan formed from UDP-glucose and is found in certain plant cell walls.
    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:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
    GO:0009555    pollen development    The process whose specific outcome is the progression of the pollen grain over time, from its formation to the mature structure. The process begins with the meiosis of the microsporocyte to form four haploid microspores. The nucleus of each microspore then divides by mitosis to form a two-celled organism, the pollen grain, that contains a tube cell as well as a smaller generative cell. The pollen grain is surrounded by an elaborate cell wall. In some species, the generative cell immediately divides again to give a pair of sperm cells. In most flowering plants, however this division takes place later, in the tube that develops when a pollen grain germinates.
    GO:0009651    response to salt stress    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating an increase or decrease in the concentration of salt (particularly but not exclusively sodium and chloride ions) in the environment.
    GO:0005985    sucrose metabolic process    The chemical reactions and pathways involving sucrose, the disaccharide fructofuranosyl-glucopyranoside.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
