Mitochondrial deoxyguanosine kinase (DGUOK) catalyzes the reactions of deoxyadenosine, deoxyguanosine, and deoxyinosine with ATP to form the corresponding nucleotide monophosphates and ADP (Park and Ives 1988; Johansson and Karlson 1996). Crystallographic studies of the human enzyme have confirmed its dimeric structure and allowed identification of key amino acid residues responsible for its substrate specificity (Johansson et al. 2001).
