# The Rfree set reported in the structure factor files available from the PDB were used for Rfree calculation.
* In the case of 1qy6, the structure factor set does not indicate excluded reflections for Rfree calculation set and the Rfree set was generated by HKL-3000 (3).
** Clashscore, rotamer outliers, and the number of residues in the Ramachandran plot favored regions were calculated using MolProbity (2)
