Figure 3.
Electron density maps are shown. (a) Single-wavelength anomalous dispersion (SAD) phasing using the PHASER software (McCoy et al., 2007 ▶). (b) Solvent flattening with the DM software package (Cowtan, 1994 ▶). (c) Automatic building using wARP (Langer et al., 2008 ▶). (d) Final map after refinement. The correlation between the respective maps and the final, refined electron density d is indicated. All maps are contoured at 1.0σ.
