Cytochrome c oxidase electron-density maps. Electron-density maps calculated from the BioMAX CcO data extending to 3.6 Å resolution. (a) 2Fo − Fc electron-density map contoured at 1.0σ around haem a3. (b) OMIT map calculated around haem a3 using phenix.polder (Liebschner et al., 2017) contoured at 3.0σ around haem a3. |
