- ProteinUMP-CMP kinase
- StatusUniProtKB unreviewed (TrEMBL)
- Amino acids245 (go to sequence)
- Protein existenceInferred from homology
- Annotation score4/5
Function
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.
Catalytic activity
- CMP + ATP = CDP + ADP
Cofactor
Note: Binds 1 Mg2+ ion per monomer.

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