Protein

Nitric oxide synthase, inducible

Gene

nos2

Organism
Carassius auratus (Goldfish)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

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 (By similarity).By similarity

Catalytic activityi

2 L-arginine + 3 NADPH + 4 O2 = 2 L-citrulline + 2 nitric oxide + 3 NADP+ + 4 H2O.

Cofactori

Protein has several cofactor binding sites:
  • hemeBy similarity
  • FADBy similarityNote: Binds 1 FAD.By similarity
  • FMNBy similarityNote: Binds 1 FMN.By similarity
  • 5,6,7,8-tetrahydrobiopterinBy similarityNote: Tetrahydrobiopterin (BH4). May stabilize the dimeric form of the enzyme.By similarity

Enzyme regulationi

Not stimulated by calcium/calmodulin.By similarity
