Protein attributes

Sequence length	1144 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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. 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 specificity	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.
