Abstract

Nitric oxide synthase (NOS) enzymes produce nitric oxide (NO) by catalyzing a five-electron oxidation of a guanidino nitrogen of L-arginine (L-Arg). Oxidation of L-Arg to L-citrulline occurs via two successive monooxygenation reactions producing N(omega)-hydroxy-L-arginine as an intermediate. 2 mol of O(2) and 1.5 mol of NADPH are consumed per mole of NO formed [PubMed8782597].

Arginine-derived NO synthesis has been identified in mammals, fish, birds, invertebrates, plants, and bacteria [PubMed8782597]. Best studied are mammals, where three distinct genes encode NOS isozymes: neuronal (nNOS or NOS-1), cytokine-inducible (iNOS or NOS-2) and endothelial (eNOS or NOS-3) [PubMed7510950]. iNOS and nNOS are soluble and found predominantly in the cytosol, while eNOS is membrane associated. The enzymes exist as homodimers, each monomer consisting of two major domains: an N-terminal oxygenase domain, which belongs to the class of heme-thiolate proteins, and a C-terminal reductase domain, which is homologous to NADPH:P450 reductase . The interdomain linker between the oxygenase and reductase domains contains a calmodulin (CaM)-binding sequence. NOSs are the only enzymes known to simultaneously require five bound cofactors animal NOS isozymes are catalytically self-sufficient. The electron flow in the NO synthase reaction is: NADPH --> FAD --> FMN --> heme --> O(2).

eNOS localisation to endothelial membranes is mediated by cotranslational N-terminal myristoylation and post-translational palmitoylation [PubMed9199168]. The subcellular localisation of nNOS in skeletal muscle is mediated by anchoring of nNOS to dystrophin. nNOS contains an additional N-terminal domain, the PDZ domain [PubMed7535955]. Some bacteria, like Bacillus halodurans, Bacillus subtilis or Deinococcus radiodurans, contain homologs of NOS oxygenase domain. The pattern is directed against the N-terminal heme binding site.
