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}.
