Crystal structure of the FYCO1 RUN domain. (a) Overall structure of the FYCO1 RUN domain. The N- and C-termini and the structural elements are labelled. (b) Electron-density map of the phenylalanine residues in the native crystal. The 2Fo − Fc difference electron-density map is contoured at the 1.5σ level with a blue mesh. The hole in the aromatic ring is clearly visible in the density map. (c) Electron-density map of water molecules. The 2Fo − Fc difference electron-density map is contoured at the 1.0σ level with a blue mesh. (d) Electron density of the mercury-derivatized crystal at 1.6 Å resolution. The 2Fo − Fc difference electron-density map is contoured at the 1.5σ level with a blue mesh. The anomalous difference Fourier map is contoured at the 5.0σ level with a red mesh. |
