The Fo–Fc omit electron density maps (green mesh, contoured at 3σ) and final models of the heme active sites of the ferric sw MbIII–nitrite adducts. (A) wt MbIII–nitrite at 1.85 Å resolution (PDB ID: 5UT7), (B) H64A MbIII–nitrite at 1.85 Å resolution (PDB ID: 5UT9), (C) H64Q MbIII–nitrite at 1.81 Å resolution (PDB ID: 5UTA), (D) V68A/I107Y MbIII–nitrite at 1.57 Å resolution (PDB ID: 5UTD). The 2Fo–Fc maps are shown in Figure S9.
