Crystal structures of human endothelial nitric oxide synthase (eNOS) and, human inducible NOS (iNOS) catalytic domains were solved in complex with, the arginine substrate and an inhibitor S-ethylisothiourea (SEITU), respectively. The small molecules bind in a narrow cleft within the larger, active-site cavity containing heme and tetrahydrobiopterin. Both are, hydrogen-bonded to a conserved glutamate (eNOS E361, iNOS E377). The, active-site residues of iNOS and eNOS are nearly identical. Nevertheless, structural comparisons provide a basis for design of isozyme-selective, inhibitors. The high-resolution, refined structures of eNOS (2.4 A, resolution) and iNOS (2.25 A resolution) reveal an unexpected structural, zinc situated at the intermolecular interface and coordinated by four, cysteines, two from each monomer.
