Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

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.

    Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
    100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
    90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
    50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
