CC   -!- FUNCTION: Involved in the biosynthesis of the central metabolite
CC       phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of
CC       pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib-
CC       5-P). {ECO:0000255|HAMAP-Rule:MF_00583}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + D-ribose 5-phosphate = 5-phospho-alpha-D-ribose 1-
CC         diphosphate + AMP + H(+); Xref=Rhea:RHEA:15609, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:58017, ChEBI:CHEBI:78346,
CC         ChEBI:CHEBI:456215; EC=2.7.6.1; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00583};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00583};
CC       Note=Binds 2 Mg(2+) ions per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_00583};
CC   -!- PATHWAY: Metabolic intermediate biosynthesis; 5-phospho-alpha-D-ribose
CC       1-diphosphate biosynthesis; 5-phospho-alpha-D-ribose 1-diphosphate from
CC       D-ribose 5-phosphate (route I): step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_00583}.
CC   -!- SUBUNIT: Homohexamer. {ECO:0000255|HAMAP-Rule:MF_00583}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00583}.
CC   -!- SIMILARITY: Belongs to the ribose-phosphate pyrophosphokinase family.
CC       Class I subfamily. {ECO:0000255|HAMAP-Rule:MF_00583}.
