CC -!- FUNCTION: Catalyzes the phosphorylation of ribose at O-5 in a reaction
CC requiring ATP and magnesium. The resulting D-ribose-5-phosphate can
CC then be used either for sythesis of nucleotides, histidine, and
CC tryptophan, or as a component of the pentose phosphate pathway.
CC {ECO:0000256|HAMAP-Rule:MF_03215}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + D-ribose = ADP + D-ribose 5-phosphate + H(+);
CC Xref=Rhea:RHEA:13697, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:47013, ChEBI:CHEBI:78346, ChEBI:CHEBI:456216;
CC EC=2.7.1.15; Evidence={ECO:0000256|ARBA:ARBA00000691,
CC ECO:0000256|HAMAP-Rule:MF_03215};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03215};
CC Note=Requires a divalent cation, most likely magnesium in vivo, as an
CC electrophilic catalyst to aid phosphoryl group transfer. It is the
CC chelate of the metal and the nucleotide that is the actual substrate.
CC {ECO:0000256|HAMAP-Rule:MF_03215};
CC -!- ACTIVITY REGULATION: Activated by a monovalent cation that binds near,
CC but not in, the active site. The most likely occupant of the site in
CC vivo is potassium. Ion binding induces a conformational change that may
CC alter substrate affinity. {ECO:0000256|HAMAP-Rule:MF_03215}.
CC -!- PATHWAY: Carbohydrate metabolism; D-ribose degradation; D-ribose 5-
CC phosphate from beta-D-ribopyranose: step 2/2. {ECO:0000256|HAMAP-
CC Rule:MF_03215}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_03215}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03215}.
CC Nucleus {ECO:0000256|HAMAP-Rule:MF_03215}.
CC -!- SIMILARITY: Belongs to the carbohydrate kinase PfkB family. Ribokinase
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_03215}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_03215}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
