additional information
the deletion mutants rDm-dNKDELTAC10 and rDm-dNKDELTAC20 show the same substrate activity pattern as the recombinant wild-type enzyme. Relative phosphorylation of 2'-deoxycytidine and 2-chloro-2'-deoxyadenosine increases with increasing C-terminal truncation. The relative activities of rDm-dNKDELTAC10 and rDm-dNKDELTAC20 with deoxyribonucleosides remains largely unchanged, whereas there is a substantial decrease in the phosphorylation of the purine ribonucleosides adenosine and guanosine, as well as of all dideoxyribonucleosides and 3'-azido-2',3'-dideoxythymidine. The relative activities with the pyrimidine ribonucleosides and 1-beta-D-arabinofuranosylcytosine and 1-beta-D-arabinofuranosylthymine are not affected by the C-terminal deletions
