In enzymology, an arginine kinase (EC 2.7.3.3) is an enzyme that catalyzes the chemical reaction

ATP + L-arginine ADP + Nω-phospho-L-arginine

Thus, the two substrates of this enzyme are ATP and L-arginine, whereas its two products are ADP and Nω-phospho-L-arginine.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a nitrogenous group as acceptor. The systematic name of this enzyme class is ATP:L-arginine Nω-phosphotransferase. Other names in common use include arginine phosphokinase, adenosine 5'-triphosphate: L-arginine phosphotransferase, adenosine 5'-triphosphate-arginine phosphotransferase, ATP:L-arginine N-phosphotransferasel ATP:L-arginine, and ω-N-phosphotransferase. This enzyme participates in arginine and proline metabolism.
