PDB_REDO: constructive validation, more than just looking for errors (2012, background): “…the mFo DFc map at the position of the oxygen, the 2mFo DFc map of the whole peptide and a combination of the two fits and the geometry, while maintaining or improving the backbone torsion angles with respect to the Ramachandran plot (Ramachandran et al., 1963) of the two residues involved.”
A fresh look at the Ramachandran plot and the occurrence of standard structures in proteins (2010, background): “It is from the origins of this unmistakable plot, based on treating atoms as simple impenetrable spheres (2, 4), that we get the widespread conceptual framework that alanine-like residues (those residues that are not glycine nor proline) can occupy one of three major ‘allowed’ regions (Figure 1): tw”
MolProbity’s Ultimate Rotamer-Library Distributions for Model Validation (2016, methodology): “Along with Ramachandran backbone φ, ψ analysis [7, 8], these libraries form the conformational criteria used in a variety of applications including crystallographic model building and refinement [9, 10, 11, 12, 13, 14], protein structure prediction and design [15, 16, 17], and protein model validati”
The Victor/FRST Function for Model Quality Estimation (2005, unknown): “The torsion angle potential (TORS) is derived from the propensities of each amino acid to adopt different combinations of (phi,psi) torsion angles (Ramachandran et al. , 1963).”
The General Projected Normal Distribution of Arbitrary Dimension: Modeling and Bayesian Inference (2017, background): “A related but different simplified description leads to the Ramachandran plot, which uses different pairs of angles to describe the backbone structure (Ramachandran et al., 1963).”
Defining and searching for structural motifs using DeepView/Swiss-PdbViewer (2012, background): “Subsequently, a variety of further patterns and regularities ( e.g. , [2-4]) in protein structures have been found, that have proven useful in the context of protein structure determination and quality assessment of determined structures.”
