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
CC pathway. {ECO:0000256|ARBA:ARBA00025301}.
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 Evidence={ECO:0000256|RuleBase:RU364099};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946,
CC ECO:0000256|RuleBase:RU364099};
CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via salvage pathway; IMP
CC from hypoxanthine: step 1/1. {ECO:0000256|ARBA:ARBA00004669,
CC ECO:0000256|RuleBase:RU364099}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000256|ARBA:ARBA00011881}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|RuleBase:RU364099}.
CC -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC family. {ECO:0000256|ARBA:ARBA00008391, ECO:0000256|RuleBase:RU364099}.
