Figure 4
2.5 Å resolution electron density for the C-terminal helix (model coordinates) generated using different SAS phases. The SAS phases were improved through solvent flattening. The maps were contoured at 1σ. (a) SAS phases were calculated using anomalous scattering of only Ca²⁺. (b). SAS phases were calculated using anomalous scattering of Ca²⁺ and 14 S atoms.
