Estimation of anomalous signal. (a) 〈d′′/sig〉 plots from SHELXC as a function of resolution. HEWL and ETR1 show significant anomalous signal, whereas the PfActI-G1 complex crystal displays only a moderate anomalous signal up to a resolution of 1.8 Å. The dashed line (light grey) is drawn at 〈d′′/sig〉 = 0.8, which is considered to be zero anomalous signal. (b) The correlation coefficient of anomalous difference of two random half data sets [CC1/2(anom)] from XSCALE is plotted against resolution shell. |
