This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:deoxynucleoside 5'-phosphotransferase. Other names in common use include multispecific deoxynucleoside kinase, ms-dNK, multisubstrate deoxyribonucleoside kinase, multifunctional deoxynucleoside kinase, D. melanogaster deoxynucleoside kinase, and Dm-dNK.
