CC -!- FUNCTION: Phosphorylates uridine and cytidine to uridine monophosphate
CC and cytidine monophosphate. Does not phosphorylate deoxyribonucleosides
CC or purine ribonucleosides. Can use ATP or GTP as a phosphate donor.
CC {ECO:0000250|UniProtKB:Q9BZX2}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + uridine = ADP + H(+) + UMP; Xref=Rhea:RHEA:16825,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16704, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:57865, ChEBI:CHEBI:456216; EC=2.7.1.48;
CC Evidence={ECO:0000250|UniProtKB:Q9BZX2};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + cytidine = ADP + CMP + H(+); Xref=Rhea:RHEA:24674,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17562, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:60377, ChEBI:CHEBI:456216; EC=2.7.1.48;
CC Evidence={ECO:0000250|UniProtKB:Q9BZX2};
CC -!- PATHWAY: Pyrimidine metabolism; CTP biosynthesis via salvage pathway;
CC CTP from cytidine: step 1/3. {ECO:0000250|UniProtKB:Q9BZX2}.
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via salvage pathway;
CC UMP from uridine: step 1/1. {ECO:0000250|UniProtKB:Q9BZX2}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250|UniProtKB:Q9BZX2}.
CC -!- SIMILARITY: Belongs to the uridine kinase family. {ECO:0000305}.
