14) Additional branches of arg metabolism are mediated by: (a) nitric oxide synthases (NOSs) leading to production of nitric oxide (NO) and downstream nitrogenous compounds, (b) arg decarboxylase leading to agmatine and its related byproducts, and (c) arg:glycine amidinotransferase leading to guanidinoacetic acid, the immediate precursor of creatine.
