Structure of the surface-bound ubiquinone molecule. (a) The location of the surface-bound ubiquinone molecule is indicated in orange. (b) 2Fobs − Fcalc electron-density map showing electron density for this ubiquinone. Two possible conformations are shown since the electron-density map does not yield a unique orientation for the surface-bound ubiquinone molecule. This map is contoured at 1σ. |
