SWISS-MODEL WORKSPACE TUTORIAL
How can I assess geomoetrical accuracy of a structure or model?
Evaluation of model quality
is a crucial step in homology modeling. While the performance of
the automated SWISS-MODEL (Schwede
et al.) pipeline in general is continuously evaluated by
the EVA project (Koh
et al.), the quality of individual models can vary significantly.
The PROCHECK suite of programs (Laskowski et al.) assess the "stereochemical quality" of a given protein structure. The aim of PROCHECK is to assess how normal, or conversely how unusual, the geometry of the residues in a given protein structure is, as compared with stereochemical parameters derived from well-refined, high-resolution structures.
