CC   -!- FUNCTION: Catalyzes the phosphorylation of ribose at O-5 in a
CC       reaction requiring ATP and magnesium. The resulting D-ribose-5-
CC       phosphate can then be used either for sythesis of nucleotides,
CC       histidine, and tryptophan, or as a component of the pentose
CC       phosphate pathway. {ECO:0000256|HAMAP-Rule:MF_01987}.
CC   -!- CATALYTIC ACTIVITY: ATP + D-ribose = ADP + D-ribose 5-phosphate.
CC       {ECO:0000256|HAMAP-Rule:MF_01987}.
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_01987};
CC       Note=Requires a divalent cation, most likely magnesium in vivo, as
CC       an electrophilic catalyst to aid phosphoryl group transfer. It is
CC       the chelate of the metal and the nucleotide that is the actual
CC       substrate. {ECO:0000256|HAMAP-Rule:MF_01987};
CC   -!- ENZYME REGULATION: Activated by a monovalent cation that binds
CC       near, but not in, the active site. The most likely occupant of the
CC       site in vivo is potassium. Ion binding induces a conformational
CC       change that may alter substrate affinity. {ECO:0000256|HAMAP-
CC       Rule:MF_01987}.
CC   -!- PATHWAY: Carbohydrate metabolism; D-ribose degradation; D-ribose
CC       5-phosphate from beta-D-ribopyranose: step 2/2.
CC       {ECO:0000256|HAMAP-Rule:MF_01987}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01987}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01987}.
CC   -!- SIMILARITY: Belongs to the carbohydrate kinase PfkB family.
CC       Ribokinase subfamily. {ECO:0000256|HAMAP-Rule:MF_01987}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation
CC       of feature annotation. {ECO:0000256|HAMAP-Rule:MF_01987}.
