General annotation (Comments)

Function

Catalyzes the phosphorylation of pyrimidine nucleoside monophosphates at the expense of ATP. Plays an important role in de novo pyrimidine nucleotide biosynthesis. Has preference for UMP and CMP as phosphate acceptors. Also displays broad nucleoside diphosphate kinase activity By similarity. HAMAP-Rule MF_03172

Catalytic activity

ATP + (d)CMP = ADP + (d)CDP. HAMAP-Rule MF_03172

ATP + UMP = ADP + UDP. HAMAP-Rule MF_03172

ATP + nucleoside diphosphate = ADP + nucleoside triphosphate. HAMAP-Rule MF_03172

Cofactor

Binds 1 magnesium ion per monomer By similarity. HAMAP-Rule MF_03172

Subunit structure

Monomer By similarity. HAMAP-Rule MF_03172

Subcellular location

Cytoplasm By similarity. Nucleus By similarity HAMAP-Rule MF_03172.

Domain

Consists of three domains, a large central CORE domain and two small peripheral domains, NMPbind and LID, which undergo movements during catalysis. The LID domain closes over the site of phosphoryl transfer upon ATP binding. Assembling and dissambling the active center during each catalytic cycle provides an effective means to prevent ATP hydrolysis By similarity. HAMAP-Rule MF_03172

Sequence similarities

Belongs to the adenylate kinase family. UMP-CMP kinase subfamily.

Sequence caution

The sequence CAJ82118.1 differs from that shown. Reason: Erroneous initiation.
