    Functioni

    Specific kinase that phosphorylates deoxyadenosine but not any other deoxyribonucleoside, as part of the deoxyribonucleotide salvage pathway.

    Catalytic activityi

    ATP + deoxyadenosine = ADP + dAMP.1 Publication

    Kineticsi

    Catalytic efficiency is 100-fold higher for deoxyadenosine than for thymidine.

    1. KM=4 µM for thymidine1 Publication
    2. KM=22.7 µM for deoxyadenosine1 Publication
    3. KM=146 µM for fludarabine1 Publication
