(deoxy)nucleoside-phosphate kinase

In enzymology, a (deoxy)nucleoside-phosphate kinase is an enzyme that catalyzes the chemical reaction


 * ATP + deoxynucleoside phosphate $$\rightleftharpoons$$ ADP + deoxynucleoside diphosphate

Thus, the two substrates of this enzyme are ATP and deoxynucleoside phosphate, whereas its two products are ADP and deoxynucleoside diphosphate.

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 and.
