== Function ==
 +
[https://www.uniprot.org/uniprot/NOS3_BOVIN NOS3_BOVIN] 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.

== Publication Abstract from PubMed ==
 +
Analyzing the active site topology and plasticity of nitric oxide synthase (NOS) and understanding enzyme-drug interactions are crucial for the development of potent, isoform-selective NOS inhibitors. A small hydrophobic pocket in the active site is identified in the bovine eNOS heme domain structures complexed with potent isothiourea inhibitors: seleno analogue of S-ethyl-isothiourea, S-isopropyl-isothiourea, and 2-aminothiazoline, respectively. These structures reveal the importance of nonpolar van der Waals contacts in addition to the well-known hydrogen bonding interactions between inhibitor and enzyme. The scaffold of a potent NOS inhibitor should be capable of donating hydrogen bonds to as well as making nonpolar contacts with amino acids in the NOS active site.
