Validation of the accuracy of MAD-phased electron density. Two segments are shown from electron-density maps of the DnaK SBD (Zhu et al., 1996BB247): a bound substrate peptide (top) and strand β3 (bottom). The direct experimental map at 2.3 Å resolution (no density modification) is shown in (a) and the 2Fo − Fc map after refinement at 2.0 Å resolution is shown in (b). The refined atomic model is superimposed onto the maps in both (a) and (b). Reproduced from Zhu et al. (1996BB247) with permission from AAAS.
