Comments [?]

FUNCTIONInvolved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P).
CATALYTIC ACTIVITY Reaction=D-ribose 5-phosphate + ATP = 5-phospho-alpha-D-ribose 1- diphosphate + AMP + H(+); Xref=Rhea:RHEA:15609, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:58017, ChEBI:CHEBI:78346, ChEBI:CHEBI:456215; EC=2.7.6.1;
case <OC:Bacteria> and not <FTTag:Metal>
COFACTOR Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Note=Binds 1 Mg(2+) ion per subunit.;
else
COFACTOR Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Note=Binds 2 Mg(2+) ions per subunit.;
end case
PATHWAYMetabolic intermediate biosynthesis; 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis; 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route I): step 1/1.
case <OC:Bacteria>
SUBUNITHomohexamer.
end case
SUBCELLULAR LOCATIONCytoplasm.
case <OC:Archaea>
SIMILARITYBelongs to the ribose-phosphate pyrophosphokinase family. Class III (archaeal) subfamily.
else
