  • Rsym=∑hkliIi−〈I〉∣/∑iI〉, where Ii is the ith measurement and 〈I〉 is the weighted mean of all measurements of I. 〈I〉/〈sigI〉 indicates the average of the intensity divided by its standard deviation. Numbers in parentheses refer to the respective highest resolution data shell in each dataset. Rcryst=∑∣∣Fo∣−∣Fc∣∣/∑∣Fo∣ where Fo and Fc are the observed and calculated structure factor amplitudes. Rfree same as Rcryst for 5% of the data randomly omitted from refinement. Ramachandran statistics indicate the fraction of residues in the most favored, additionally allowed and generously allowed and disallowed regions of the Ramachandran diagram as defined by PROCHECK (Laskowski et al, 1993).
