Enzyme Information
| 2.7.4.14 |
UMP/CMP kinase.
based on mapping to UniProt P20425
(1) ATP + (d)CMP = ADP + (d)CDP. (2) ATP + UMP = ADP + UDP.
-!- This eukaryotic enzyme is a bifunctional enzyme that catalyzes the phosphorylation of both CMP and UMP with similar efficiency. -!- dCMP can also act as acceptor. -!- Different from the monofunctional prokaryotic enzymes EC 2.7.4.25, CMP kinase and EC 2.7.4.22, UMP kinase. -!- This eukaryotic enzyme is a bifunctional enzyme that catalyzes the phosphorylation of both CMP and UMP with similar efficiency. -!- dCMP can also act as acceptor. -!- Different from the monofunctional prokaryotic enzymes EC 2.7.4.25 and EC 2.7.4.22. -!- Formerly EC 2.7.4.5.
