molecular function
    GO:0052657    guanine phosphoribosyltransferase activity    Catalysis of the reaction: GMP + diphosphate = guanine + 5-phospho-alpha-D-ribose 1-diphosphate.
    GO:0004422    hypoxanthine phosphoribosyltransferase activity    Catalysis of the reaction: IMP + diphosphate = hypoxanthine + 5-phospho-alpha-D-ribose 1-diphosphate.
    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: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).
biological process
    GO:0032263    GMP salvage    Any process which produces guanosine monophosphate from derivatives of it, without de novo synthesis.
    GO:0032264    IMP salvage    Any process which produces inosine monophosphate from derivatives of it, without de novo synthesis.
    GO:0006168    adenine salvage    Any process that generates adenine, 6-aminopurine, from derivatives of it without de novo synthesis.
    GO:0006178    guanine salvage    Any process that generates guanine, 2-amino-6-hydroxypurine, from derivatives of it without de novo synthesis.
    GO:0046100    hypoxanthine metabolic process    The chemical reactions and pathways involving hypoxanthine, 6-hydroxy purine, an intermediate in the degradation of adenylate. Its ribonucleoside is known as inosine and its ribonucleotide as inosinate.
    GO:0009116    nucleoside metabolic process    The chemical reactions and pathways involving a nucleoside, a nucleobase linked to either beta-D-ribofuranose (a ribonucleoside) or 2-deoxy-beta-D-ribofuranose, (a deoxyribonucleoside), e.g. adenosine, guanosine, inosine, cytidine, uridine and deoxyadenosine, deoxyguanosine, deoxycytidine and thymidine (= deoxythymidine).
    GO:0006166    purine ribonucleoside salvage    Any process which produces a purine nucleoside from derivatives of it, without de novo synthesis.
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:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
