P97270

- NOS3_CAVPO

UniProt

P97270 - NOS3_CAVPO

Protein

Nitric oxide synthase, endothelial

Gene

NOS3

Organism
Cavia porcellus (Guinea pig)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli
  1. 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 By similarity.By similarity

    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

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