CC -!- FUNCTION: Purine salvage pathway enzyme which catalyzes the transfer of
CC the ribosyl-5-phosphate group from 5-phospho-alpha-D-ribose 1-
CC diphosphate (PRPP) to the N9 position of hypoxanthine to yield IMP
CC (inosine 5'-monophosphate). To a lesser extent, can also act on guanine
CC leading to GMP, but shows a highly less efficient activity with
CC xanthine. {ECO:0000256|ARBA:ARBA00003637}.
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 Evidence={ECO:0000256|ARBA:ARBA00000210};
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|ARBA:ARBA00001946,

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 -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|RuleBase:RU364099}.
CC -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC family. {ECO:0000256|ARBA:ARBA00008391, ECO:0000256|RuleBase:RU364099}.
