== Function ==
'''Arginine kinase''' (AK) is a phosphagen kinase which catalyzes the conversion of L-arginine and ATP to N-phospho-L-arginine and ADP. AK is part of arginine and proline metabolism. The phosphagen kinase reaction of AK is central to cellular energy homeostasis, i.e. maintenance of ATP level in invertebrates. Another phosphagen kinase found mostly in vertebrates is [[Creatine Kinase]] whose substrate is creatine.
