N(omega)-Hydroxyarginine
N-omega-hydroxy-l-arginine, also known as 6-noha, belongs to arginine and derivatives class of compounds. Those are compounds containing arginine or a derivative thereof resulting from reaction of arginine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-omega-hydroxy-l-arginine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). N-omega-hydroxy-l-arginine can be found in a number of food items such as chinese cinnamon, chervil, sugar apple, and safflower, which makes N-omega-hydroxy-l-arginine a potential biomarker for the consumption of these food products. N(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).
