Function

Adenosine kinase (AdK) catalyzes the transfer of phosphate from ATP to adenosine to produce AMP. AMP-PCP is a non-hydrolyzable ATP analog.[1]

Disease

AdK deficiency causes hypermethioninemia. Overexpression of AdK in the brain leads to decrease of adenosine and is believed as the main cause of epilepsy.

Structural highlights

AdK consists of a (PDB entry 1bx4).[2]
