In enzymology, a (deoxy)nucleoside-phosphate kinase (EC 2.7.4.13) is an enzyme that catalyzes the chemical reaction
- ATP + deoxynucleoside phosphate [math]\displaystyle{ \rightleftharpoons }[/math] ADP + deoxynucleoside diphosphate
Thus, the two substrates of this enzyme are ATP and deoxynucleoside phosphate, whereas its two products are ADP and deoxynucleoside diphosphate.[1]
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. The systematic name of this enzyme class is ATP:deoxynucleoside-phosphate phosphotransferase. Other names in common use include deoxynucleoside monophosphate kinase, deoxyribonucleoside monophosphokinase, and deoxynucleoside-5'-monophosphate kinase.
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1DEK and 1DEL.
