'''BOVINE ENDOTHELIAL NITRIC OXIDE SYNTHASE HEME DOMAIN COMPLEXED WITH 3-BROMO-7-NITROINDAZOLE (H4B PRESENT)'''<br />


==Overview==
==BOVINE ENDOTHELIAL NITRIC OXIDE SYNTHASE HEME DOMAIN COMPLEXED WITH 3-BROMO-7-NITROINDAZOLE (H4B PRESENT)==
Nitric oxide is generated under normal and pathophysiological conditions, by three distinct isoforms of nitric oxide synthase (NOS). A, small-molecule inhibitor of NOS (3-Br-7-nitroindazole, 7-NIBr) is, profoundly neuroprotective in mouse models of stroke and Parkinson's, disease. We report the crystal structure of the catalytic heme domain of, endothelial NOS complexed with 7-NIBr at 1.65 A resolution. Critical to, the binding of 7-NIBr at the substrate site is the adoption by eNOS of an, altered conformation, in which a key glutamate residue swings out toward, one of the heme propionate groups. Perturbation of the heme propionate, ensues and eliminates the cofactor tetrahydrobiopterin-heme interaction., We also present three crystal structures that reveal how alterations at, the substrate site facilitate 7-NIBr and structurally dissimilar ligands, to occupy the cofactor site.
