CC -!- FUNCTION: Converts guanine to guanosine monophosphate, and hypoxanthine
CC to inosine monophosphate. Transfers the 5-phosphoribosyl group from 5-
CC phosphoribosylpyrophosphate onto the purine. Plays a central role in
CC the generation of purine nucleotides through the purine salvage pathway
CC (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=diphosphate + IMP = 5-phospho-alpha-D-ribose 1-diphosphate +
CC hypoxanthine; Xref=Rhea:RHEA:17973, ChEBI:CHEBI:17368,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:58017, ChEBI:CHEBI:58053; EC=2.4.2.8;

CC PhysiologicalDirection=right-to-left; Xref=Rhea:RHEA:17975;
CC Evidence={ECO:0000250|UniProtKB:Q04178};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=diphosphate + GMP = 5-phospho-alpha-D-ribose 1-diphosphate +
CC guanine; Xref=Rhea:RHEA:25424, ChEBI:CHEBI:16235, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:58017, ChEBI:CHEBI:58115; EC=2.4.2.8;
CC Evidence={ECO:0000250|UniProtKB:Q04178};
CC PhysiologicalDirection=right-to-left; Xref=Rhea:RHEA:25426;
CC Evidence={ECO:0000250|UniProtKB:Q04178};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Note=The magnesium ions are essentially bound to the substrate and have
CC few direct interactions with the protein. {ECO:0000250};
CC -!- SUBUNIT: Dimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum
CC {ECO:0000269|PubMed:16823372}.
CC -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC family. {ECO:0000305}.
