Chain A,B,C,D   (UPP_TOXGO | Q26998)
molecular function
    GO:0005525    GTP binding    Interacting selectively and non-covalently with GTP, guanosine triphosphate.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    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).
    GO:0004845    uracil phosphoribosyltransferase activity    Catalysis of the reaction: diphosphate + UMP = 5-phospho-alpha-D-ribose 1-diphosphate + uracil.
biological process
    GO:0044206    UMP salvage    Any process which produces UMP, uridine monophosphate, from derivatives of it (e.g. cytidine, uridine, cytosine) without de novo synthesis.
    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.
