Figure 5
The experimental electron-density map (a) and corresponding diffraction pattern (b) of a large crystal with good microscopic order compensating for poor macroscopic order: high mosaicity and multiple crystals. Data correspond to PDB entry 1xvi
. The initial model was built by RESOLVE in the fast mode. For picture clarity, only a Cα trace is presented. It is important to note that a poor-quality crystal was used because it was the only crystal available for structure solution. |
