Figure 2
Electron-density maps of the modelled peroxides. The left panel shows 2Fo − Fc electron densities for all of the peroxide molecules modelled in the treated Gln143Asn structure (blue mesh) at the indicated contour levels. To validate this, we ran refinement trials where each Lb was replaced by a fully occupied water (middle panel) as in the resting-state structure (right panel). The Fo − Fc difference densities (green mesh, contoured to 3.0σ) in the middle trial panels indicate the need to model two O atoms in the treated structure, rather than one as in the resting state. Moreover, the 2Fo − Fc density is elongated for the Lb sites in the treated structure (blue mesh), whereas it appears more spherical in the resting state (purple mesh). |
