Arginine kinase

In enzymology, arginine kinase (EC 2.7.3.3) is an enzyme that catalyzes the chemical reaction In enzymology, arginine kinase (EC 2.7.3.3) is an enzyme that catalyzes the chemical reaction 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. As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes 1BG0​, 1M15​, 1M80​, 1P50​, 1P52​, 1RL9​, 1SD0​, and 2J1Q​.
