Protein attributes

Sequence length	1153 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In macrophages, NO mediates tumoricidal and bactericidal actions.
Catalytic activity	L-arginine + n NADPH + n H+ + m O2 = citrulline + nitric oxide + n NADP+.
Cofactor	Heme group By similarity. Binds 1 FAD By similarity. Binds 1 FMN By similarity. Tetrahydrobiopterin (BH4). May stabilize the dimeric form of the enzyme By similarity.
Enzyme regulation	Regulated 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 By similarity.
Subunit structure	Homodimer. Binds SLC9A3R1.
Tissue specificity	Expressed in the liver, retina, bone cells and airway epithelial cells of the lung. Not expressed in the platelets.
Induction	By endotoxins and cytokines. Induced by interferon gamma acting synergistically with lipopolysaccharide, tumor necrosis factor alpha or interleukin-1 beta. Ref.14
Sequence similarities	Belongs to the NOS family. Contains 1 FAD-binding FR-type domain. Contains 1 flavodoxin-like domain.
