Metabolite Identification
Common NameN(omega)-Hydroxyarginine
DescriptionN(omega)-Hydroxyarginine is a product of the arginine-nitric oxide pathway, and is the first intermediate in the process catalyzed by nitric oxide synthase (NOS) (EC 1.14.13.99). NOS is a heme protein that catalyzes the oxygenation of L-arginine in the presence of NADPH to form nitric oxide and citrulline. N(omega)-Hydroxyarginine appears to interfere with cell proliferation/cell growth by inhibiting arginase, a binuclear Mn(2+) metalloenzyme that catalyzes the hydrolysis of L-arginine to L-ornithine and urea (EC 3.5.3.1). Arginase has 6R-tetrahydrobiopterin (H4B) as an enzyme-bound cofactor (PMID: 11259671 , 11258880 , 14504282 , 9735327 ).
