CC -!- FUNCTION: Catalyzes a salvage reaction resulting in the formation of
CC IMP that is energically less costly than de novo synthesis.
CC {ECO:0000255|HAMAP-Rule:MF_01467}.
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:0000255|HAMAP-Rule:MF_01467};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=diphosphate + GMP = 5-phospho-alpha-D-ribose 1-diphosphate +

CC ChEBI:CHEBI:58017, ChEBI:CHEBI:58115; EC=2.4.2.8;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01467};
CC -!- PATHWAY: Purine metabolism; IMP biosynthesis via salvage pathway; IMP
CC from hypoxanthine: step 1/1. {ECO:0000255|HAMAP-Rule:MF_01467}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01467}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01467}.
CC -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC family. Archaeal HPRT subfamily. {ECO:0000255|HAMAP-Rule:MF_01467}.
