Hydrophobic pocket accommodating the chlorophenyl aromatic ring of AR-R17477 bound to rat nNOSoxy. For the residues Y706, L337, M336, W678, and W306 of the second molecule in nNOSoxy biological dimer (W306*), the van der Waals surface is shown. The color scheme of the surface corresponds to the atom charge (blue, positive; red, negative; white, neutral).
