Electron density maps showing (a) an overview of part of the 2Fo − Fc map of the full particle contoured at 2σ, (b) an Fo − Fc omit map of the region of one of the haem groups contoured at 3σ, and (c) 2Fo − Fc (at 2σ, blue) and Fo − Fc (at 4σ, green) maps of the region of a predicted calcium binding site. |
