GN Name=NOS3; Synonyms=ENOS; OS Ovis aries (Sheep).

OX NCBI_TaxID=9940; RN [1] RP NUCLEOTIDE SEQUENCE. RC TISSUE=Endothelial cells; RA Aguan K., Weiner C.P.; RT "Effect of hypoxia on the microvasculature of developing fetal brain RT of sheep: a studies on the expression pattern of constitutive forms of RT nitric oxide synthase."; RL Submitted (OCT-1996) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Produces nitric oxide (NO) which is implicated in CC vascular smooth muscle relaxation through a cGMP-mediated signal CC transduction pathway. No mediates vascular endothelial growth CC factor (VEGF)-induced angiogenesis in coronary vessels and CC promotes blood clotting through the activation of platelets (By CC similarity). CC -!- CATALYTIC ACTIVITY: L-arginine + n NADPH + m O(2) = citrulline + CC nitric oxide + n NADP(+). CC -!- COFACTOR: Heme. Binds one mole each of FAD and FMN. Also requires CC tetrahydrobiopterin (BH4) which may stabilize the dimeric form of CC the enzyme (By similarity). CC -!- ENZYME REGULATION: Stimulated by calcium/calmodulin (By CC similarity). CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SIMILARITY: Belongs to the NOS family.
