Summary
Ramachandran plot (phi, psi backbone torsion angles) for general-case amino acids - no Gly, Pro, prePro, Ile, or Val. Datapoints from the "Top8000" crystal-structure chains with both resolution and MolProbity score <2.0, non-redundant at the PDB's 70% clusters, and each point with backbone B-factors ≤30. Inner contour encloses 98% of this high-quality data (favored region); outer contour encloses 99.95% (allowed) and excludes 0.05% (outlier or disallowed region). Methodology from [1] and [2].
