Figure 2
Typical b (red), intermediate (yellow) and c (blue) positions of the Rieske domain after focused 3D classification and refinement (a, b, c) and a superposition of the three models (d). The range of different positions of the Rieske domain in all samples is visualized in the plot of the distances between Fe2 in the [2Fe–2S] cluster and Fe of heme bL and heme c1, respectively (e). The three positions in (a)–(d) are marked by dashed circles in (e). |
