Adenosine kinase

Gene

Adk

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

ATP dependent phosphorylation of adenosine and other related nucleoside analogs to monophosphate derivatives. Serves as a potential regulator of concentrations of extracellular adenosine and intracellular adenine nucleotides.

Catalytic activityi

ATP + adenosine = ADP + AMP.

Cofactori

Mg2+By similarityNote: Binds 3 Mg2+ ions per subunit.By similarity

Pathwayi: AMP biosynthesis via salvage pathway

This protein is involved in step 1 of the subpathway that synthesizes AMP from adenosine.
Proteins known to be involved in this subpathway in this organism are:
  1. Adenosine kinase (Adk)
This subpathway is part of the pathway AMP biosynthesis via salvage pathway, which is itself part of Purine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes AMP from adenosine, the pathway AMP biosynthesis via salvage pathway and in Purine metabolism.

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.
