Protein

Nitric oxide synthase, endothelial

Gene
Nos3, Ecnos
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Produces nitric oxide (NO) which is implicated in vascular smooth muscle relaxation through a cGMP-mediated signal transduction pathway. NO mediates vascular endothelial growth factor (VEGF)-induced angiogenesis in coronary vessels and promotes blood clotting through the activation of platelets. May play a significant role in normal and abnormal limb development.1 Publication

Catalytic activityi

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

Cofactori

Heme group.
Binds 1 FAD.
Binds 1 FMN.
Tetrahydrobiopterin (BH4). May stabilize the dimeric form of the enzyme.

Enzyme regulationi

Stimulated by calcium/calmodulin. Inhibited by NOSIP and NOSTRIN By similarity.
