Figure 7
2mFo − DFc electron-density maps at 0.7σ level showing the poorly defined surface-residue Arg128 generated from datasets consisting of different numbers of merged diffraction patterns: (a) in yellow, 750 patterns; (b) in pink, 1 500 patterns; (c) in cyan, 3 000 patterns; and (d) in green, all patterns (24 344). Whereas in (a) and (b) the electron density is ambiguous, the merged datasets from 3 000 (c) and all 24 344 patterns (d) clearly reveal a second conformation of Arg128.
