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.
Structural studies
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.
