2.7.4.25 ATP + CMP - 2.7.4.25 ATP + dCMP - 2.7.4.25 ATP + dCMP Escherichia coli CMPK phosphorylates dCMP nearly as well as it does CMP 2.7.4.25 additional information bacterial CMP kinases are specific for CMP and dCMP, whereas the related eukaryotic NMP kinase phosphorylates CMP and UMP with similar efficiency. Bacterial CMP kinase has a narrower NMP-binding pocket and a hydrogen-bonding network involving the pyrimidine moiety specific for the cytosine nucleobase compared to eukaryotic UMP?CMP kinases
