Values in parentheses refer to the last resolution shell.
Rsym = ΣhΣi|I(h,i)−I(h)|/ΣhΣi I(h,i) where I(h,i) are symmetry related intensities and I(h) is the mean intensity of the reflection with unique index h.
Rcryst (%) = Σ|Fo − Fc|/ΣFo, where, Fo is the observed structure factor amplitude, and Fc is the structure factor calculated from the model.
Rfree (%) is calculated in the same manner as Rcryst using 5% of all reflections excluded from refinement stages using high-resolution data.
R.M.S.D., root-mean-square deviation.
Percentage of residues in the “most favored region” of the Ramachandran plot and percentage of outliers (PROCHECK).
