UMP-CMP kinase

Gene

KCY

Organism
Esox lucius (Northern pike)
Status
Unreviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

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.UniRule annotation

Catalytic activityi

ATP + (d)CMP = ADP + (d)CDP.UniRule annotation
ATP + UMP = ADP + UDP.UniRule annotation
ATP + nucleoside diphosphate = ADP + nucleoside triphosphate.UniRule annotation

Cofactori

Mg2+UniRule annotationNote: Binds 1 Mg2+ ion per monomer.UniRule annotation

Domaini

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.UniRule annotation

Sequence similaritiesi

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