Rwork and Rfree values resulting from different refinement strategies. (a) R values after refinement with increasing numbers of parameters, including data to 4.0 Å resolution. (b) Differences in R values after refinement (all atom coordinates, individual B factors) depending on the chosen high-resolution data cutoff. Models were refined in parallel to both the lower and the higher resolution cutoff and the R values were compared at the lower cutoff. The range of lower data quality between 3.6 and 3.4 Å is probably caused by high background scattering owing to the solvent.
