CC -!- FUNCTION: Catalyzes the phosphorylation of pyrimidine nucleoside
CC monophosphates at the expense of ATP. Plays an important role in de
CC novo pyrimidine nucleotide biosynthesis. Has preference for UMP and CMP
CC as phosphate acceptors. {ECO:0000255|HAMAP-Rule:MF_03172}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + CMP = ADP + CDP; Xref=Rhea:RHEA:11600,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:58069, ChEBI:CHEBI:60377,
CC ChEBI:CHEBI:456216; EC=2.7.4.14; Evidence={ECO:0000255|HAMAP-

CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + dCMP = ADP + dCDP; Xref=Rhea:RHEA:25094,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:57566, ChEBI:CHEBI:58593,
CC ChEBI:CHEBI:456216; EC=2.7.4.14; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_03172};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + UMP = ADP + UDP; Xref=Rhea:RHEA:24400,

CC ChEBI:CHEBI:456216; EC=2.7.4.14; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_03172};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03172};
CC Note=Binds 1 Mg(2+) ion per monomer. {ECO:0000255|HAMAP-Rule:MF_03172};
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_03172}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03172}.
CC Nucleus {ECO:0000255|HAMAP-Rule:MF_03172}.
CC -!- DOMAIN: Consists of three domains, a large central CORE domain and two
CC small peripheral domains, NMPbind and LID, which undergo movements
CC during catalysis. The LID domain closes over the site of phosphoryl
CC transfer upon ATP binding. Assembling and dissambling the active center
CC during each catalytic cycle provides an effective means to prevent ATP
CC hydrolysis. {ECO:0000255|HAMAP-Rule:MF_03172}.
CC -!- SIMILARITY: Belongs to the adenylate kinase family. UMP-CMP kinase
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_03172}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAR24708.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
CC Sequence=CAA23069.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=CAB81339.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
