CC   -!- FUNCTION: Catalyzes a salvage reaction resulting in the formation of
CC       AMP, that is energically less costly than de novo synthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00004}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=AMP + diphosphate = 5-phospho-alpha-D-ribose 1-diphosphate +
CC         adenine; Xref=Rhea:RHEA:16609, ChEBI:CHEBI:16708, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:58017, ChEBI:CHEBI:456215; EC=2.4.2.7;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00004};
CC   -!- PATHWAY: Purine metabolism; AMP biosynthesis via salvage pathway; AMP
CC       from adenine: step 1/1. {ECO:0000255|HAMAP-Rule:MF_00004}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00004}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00004}.
CC   -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC       family. {ECO:0000255|HAMAP-Rule:MF_00004}.
