Cytosolic adenosine kinase (ADK) catalyzes the reactions of adenosine and deoxyadenosine with ATP to yield the corresponding nucleotide monophosphates and ADP (Andres and Fox 1979). The enzyme is substantially more active on adenosine than deoxyadenosine in vitro (Hurley at al. 1985) though studies of cultured cells suggest that both reactions may be physiologically relevant (Hershfield et al. 1982). The enzyme is a monomer complexed with magnesium (Mathews et al. 1998).
