Comments [?]

case <OC:Vertebrata>
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.
Catalytic activity RHEA:11600: ATP + CMP = ADP + CDP
EC 2.7.4.14
RHEA:25094: ATP + dCMP = ADP + dCDP
EC 2.7.4.14
RHEA:44640: a 2'-deoxyribonucleoside 5'-diphosphate + ATP = a 2'-deoxyribonucleoside 5'-triphosphate + ADP
EC 2.7.4.6
RHEA:18113: a ribonucleoside 5'-diphosphate + ATP = a ribonucleoside 5'-triphosphate + ADP
EC 2.7.4.6
else case <OC:Fungi>
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 dUMP as phosphate acceptors, but can also use CMP, dCMP and AMP.

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