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         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}.
