      Background InformationNitric oxide (NO) is an inorganic, gaseous free radical that carries a variety of messages between cells. Vasorelaxation, neurotransmission and cytotoxicity can all be potentiated through cellular response to NO. NO production is mediated by members of the nitric oxide synthase (NOS) family. NOS catalyzes the oxidization of L-arginine to produce L-citrulline and NO. Two constitutive isoforms, brain or neuronal NOS (b or nNOS, type I) & endothelial cell NOS (eNOS, type III), and one inducible isoform (iNOS, type II), have been cloned. Cytokines such as interferon-gamma (IFN), tumor necrosis factor (TNF), interleukin-1 and -2, and lipopolysaccarides (LPS) cause an increase in iNOS mRNA, protein, and activity levels. Protein kinase C-stimulating agents exhibit the same effect on iNOS activity. Human iNOS is regulated by calcium/calmodulin (in contrast with mouse NOS2).

      UniProt Number
      UniProt SummaryFUNCTION: Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In macrophages, NO mediates tumoricidal and bactericidal actions. Also has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such COX2.

      CATALYTIC ACTIVITY: L-arginine + n NADPH + n H+ + m O2 = citrulline + nitric oxide + n NADP+.

      COFACTOR: Heme group.

      Binds 1 FAD.

      Binds 1 FMN.

      Tetrahydrobiopterin (BH4). May stabilize the dimeric form of the enzyme.

      ENZYME REGULATION: Not stimulated by calcium/calmodulin. Aspirin inhibits expression and function of this enzyme and effects may be exerted at the level of translational/post-translational modification and directly on the catalytic activity.

      SUBUNIT STRUCTURE: Homodimer. Binds SLC9A3R1 (By similarity).

      TISSUE SPECIFICTY: Macrophages.

      INDUCTION: By treatment with endotoxins or cytokines.

      SEQUENCE SIMILARITIES: Belongs to the NOS family.

      Contains 1 FAD-binding FR-type domain.

      Contains 1 flavodoxin-like domain.
