Thus, the two substrates of this enzyme are ATP and deoxyadenosine, whereas its two products are ADP and dAMP.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:deoxyadenosine 5'-phosphotransferase. This enzyme is also called purine-deoxyribonucleoside kinase. This enzyme participates in purine metabolism.
