'''Nitric Oxide Synthase''' (NOS) is an enzyme catalysing the formation of L-citrulline and [http://en.wikipedia.org/wiki/Nitric_Oxide/ nitric oxide] (NO) from L-arginine. NOS is a homodimeric protein with 125- to 160-kDa per monomer. | '''Nitric Oxide Synthase''' (NOS) is an enzyme catalysing the formation of L-citrulline and [http://en.wikipedia.org/wiki/Nitric_Oxide/ nitric oxide] (NO) from L-arginine. NOS is a homodimeric protein with 125- to 160-kDa per monomer. In mammals, NOS appears as 3 isozymes: neuronal NOS (nNOS), cytokine-inducible NOS (iNOS) and endothelial NOS (eNOS). The N-terminal domain of NOS is an oxygenase domain (OD). NOS cofactors are: NADPH, FAD, FMN, heme and O2. | ||
