glycine amidinotransferase  M-CSA #18

Glycine amidinotransferase, also known as L-arginine:glycine amidinotransferase (AT) catalyses the committed step in creatine biosynthesis. The enzyme does this by forming guanidinoacetic acid, the immediate precursor of creatine. Both creatine and its phosphorylated form play an essential role in the energy metabolism of muscle and nerve tissues, acting as a dynamic reservoir of high-energy phosphate which buffers the rapid fluctuations of the ATP/ADP ratio during muscle and nerve action.
