Figure 2
Rhodopsin dimer in cartoon format (pink) overlaid with σA-weighted Fo − Fc difference density contoured at 2.0σ (green mesh). (a) Trp265 (cyan) fitted into σA-weighted Fo − Fc difference density. (b) Cys264, Trp265 and Leu266 (cyan) aligned to the fitted Trp265. Transmembrane helices 5 (left) and 6 (right) are visible behind the translated peptide. (c) A translated rhodopsin dimer (cyan stick format) aligned with Trp265 overlaid with the main rhodopsin dimer. |
