S74E-dCK mutant in complex with UDP

Template:ABSTRACT PUBMED 21351740

Function

[DCK_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]
