Refinement | Method to determine structure: Re-refinement using ensemble model Starting model: PDB entry 1ZXU Resolution: 1.7→37.68 Å / Rfactor Rfree error: 0.006 / Data cutoff high absF: 1125214.625 / Data cutoff low absF: 0 / Isotropic thermal model: RESTRAINED / Cross valid method: THROUGHOUT / σ(F): 0 Stereochemistry target values: maximum likelihood using amplitudes Details: This PDB entry is a re-refinement using an ensemble model of the previously deposited single-conformer structure 1zxu and the first data set in the deposited structure factor file for 1zxu ...Details: This PDB entry is a re-refinement using an ensemble model of the previously deposited single-conformer structure 1zxu and the first data set in the deposited structure factor file for 1zxu along with the R-free set defined therein. The coordinates were generated by an automated protocol from an initial model consisting of 16 identical copies of the protein and non-water hetero-atoms assigned fractional occupancies adding up to one, and a single copy of the solvent molecules. Refinement was carried out with all the conformers present simultaneously and with the potential energy terms corresponding to interactions between the different conformers excluded. The helix and sheet records were calculated using coordinates from the first conformer only. The structure visualization program PYMOL is well-suited for directly viewing the ensemble model presented in this PDB file.
