CC   -!- FUNCTION: Catalyzes the phosphorylation of ribose 1,5-bisphosphate to
CC       5-phospho-D-ribosyl alpha-1-diphosphate (PRPP). {ECO:0000255|HAMAP-
CC       Rule:MF_00836}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=alpha-D-ribose 1,5-bisphosphate + ATP = 5-phospho-alpha-D-
CC         ribose 1-diphosphate + ADP; Xref=Rhea:RHEA:20109, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:58017, ChEBI:CHEBI:68688, ChEBI:CHEBI:456216;
CC         EC=2.7.4.23; Evidence={ECO:0000255|HAMAP-Rule:MF_00836};
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 II): step 3/3. {ECO:0000255|HAMAP-
CC       Rule:MF_00836}.
CC   -!- SIMILARITY: Belongs to the ribose 1,5-bisphosphokinase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00836}.
