K20pI-Phe phased anomalous difference Fourier maps, with the I atom depicted as a magenta sphere. Named and numbered residues are from Spy. (a) Phased anomalous difference Fourier maps from 5.2 keV data sets collected at two goniometer κ angles, contoured at 20σ and 12σ, respectively. (b) Phased anomalous difference Fourier map from data collected at 4.5 keV, contoured at 4.0σ. (c) Phased anomalous difference Fourier maps from data collected at 5.2 keV from three additional crystals, contoured at 20σ (crystals 2 and 3) and 9σ (crystal 4). |
