Methods have been developed to assess the stereochemical quality of any protein structure both globally and locally using various criteria. Several parameters can be derived from the coordinates of a given structure. Global parameters include the distribution of ϕ,ψ and χ1 torsion angles, and hydrogen bond energies. There are clear correlations between these parameters and resolution; as the resolution improves, the distribution of the parameters becomes more clustered. These features show a… 
Conformational analysis of protein structures derived from NMR data
A suite of programs is being developed to address the special needs of NMR‐derived structures which will take into account the existence of increased mobility in solution, as well as examining the distribution of ϕ, Ψ, and χ angles as indicators of global conformational irregularity.
On the reproducibility of protein crystal structures: five atomic resolution structures of trypsin.
Many details of a protein structure are reproducible or to what extent they might differ in models obtained from different crystals, however, several features of residues or ligands located in flexible parts of the macromolecule may vary significantly, such as side-chain orientations and the occupancies of certain fragments.
Quality of protein crystal structures.
Multivariate statistical analysis revealed that while technological improvements have increased the number of structures determined, the overall quality of structures has remained constant and the association between structure quality and the journal in which the structure was first published was striking.
Molecular mechanics calculations of proteins. Comparison of different energy minimization strategies.
It could be concluded that using the following conditions: Dielectric constant epsilon = 4 or 20; a distance dependent dielectric function and stepwise energy minimization, it is possible to reproduce X-ray structures very accurately without including explicit solvent molecules.
Macromolecular structures: Quality assessment and biological interpretation
The scientific systems in structural biology are robust and to a large extent capable of correcting any errors in interpretation of structural results, however, this process is hindered by spurious challenges to published research, based on misuse of validation mechanisms.
Analysis of the Quality of Macromolecular Structures
Structure determination utilizing X-ray crystallography involves collection of diffraction data, determination of initial phases followed by iterative rounds of model building and crystallographic

The 3D structure determination of a protein is crucial for structure-guided drug development and the homology modeling approach is the most accurate method among the computational methods, yielding
Quality assessment of NMR structures: a statistical survey.
A problem of atom overlap in a number of refined structures is identified and adhering to the standard nomenclature as put forward by an IUPAC Task Group is recommended to ensure consistency between restraints and coordinates.
Deviations from standard atomic volumes as a quality measure for protein crystal structures.
Atomic volumes, themselves not directly restrained in crystallographic refinement, can provide an independent, rather sensitive, measure of the quality of a protein structure, and it is found that the Z-score rms decreases as the resolution and R-factor improve, consistent with the fact that these improvements generally reflect more accurate models.
