FunctionDCK_HUMAN Required for the phosphorylation of the deoxyribonucleosides deoxycytidine (dC), deoxyguanosine (dG) and deoxyadenosine (dA). Has broad substrate specificity, and does not display selectivity based on the chirality of the substrate. It is also an essential enzyme for the phosphorylation of numerous nucleoside analogs widely employed as antiviral and chemotherapeutic agents.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedHuman deoxycytidine kinase (dCK) is involved in the nucleotide-biosynthesis salvage pathway and has also been shown to phosphorylate several antitumor and antiviral prodrugs. The structures of dCK alone and the dead-end complex of dCK with substrate nucleoside and product ADP or UDP have previously been reported; however, there is currently no structure available for a substrate or product complex. Here, the structures of dCK complexes with the products dCMP, UDP and Mg2+ ion, and with dAMP, UDP and Mg2+ ion are reported. Structural comparisons show that the product complexes with UDP and a dead-end complex with substrate and UDP have similar active-site conformations.
