Refinement statistics
| Alternate conformation refinement | Value |
|---|---|
| Resolution range, Å | 50–2.8 |
| Twin fraction | 0.123 |
| Protein atom | 3,630 |
| Retinal atom | 40 |
| Rcryst, % (outer shell) | 21.8 (30.5) |
| Rfree, % (outer shell) | 23.8 (32.0) |
| rmsd of bonds, Å | 0.012 |
| rmsd of angles, ° | 1.41 |
The final refinements included dual conformations of the selected residues as described in the text. Rcryst = Σhkl|Fo − Fc|/Σhkl|Fo|. Rfree values were calculated from a set of 5% randomly selected reflections that were omitted from refinement. This set was the same as that used for the dark state.
