Protein

Nitric oxide synthase, inducible

Gene

NOS2

Organism
Canis familiaris (Dog) (Canis lupus familiaris)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Catalytic activityi

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

Cofactori

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).By similarity

Enzyme regulationi

Regulated by calcium/calmodulin.By similarity
