molecular function
    GO:0008879    glucose-1-phosphate thymidylyltransferase activity    Catalysis of the reaction: alpha-D-glucose 1-phosphate + dTTP = diphosphate + dTDP-glucose.
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    GO:0000287    magnesium ion binding    Interacting selectively and non-covalently with magnesium (Mg) ions.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    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.
biological process
    GO:0009058    biosynthetic process    The chemical reactions and pathways resulting in the formation of substances; typically the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones.
    GO:0009246    enterobacterial common antigen biosynthetic process    The chemical reactions and pathways resulting in the formation of the enterobacterial common antigen, an acidic polysaccharide containing N-acetyl-D-glucosamine, N-acetyl-D-mannosaminouronic acid, and 4-acetamido-4,6-dideoxy-D-galactose. A major component of the cell wall outer membrane of Gram-negative bacteria.
    GO:0045226    extracellular polysaccharide biosynthetic process    The chemical reactions and pathways resulting in the formation of polysaccharides used in extracellular structures.
    GO:0000271    polysaccharide biosynthetic process    The chemical reactions and pathways resulting in the formation of a polysaccharide, a polymer of many (typically more than 10) monosaccharide residues linked glycosidically.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
