Peptide bond distortions from planarity: new insights from quantum mechanical calculations and peptide/protein crystal structures.

By combining quantum-mechanical analysis and statistical survey of peptide/protein structure databases we here report a thorough investigation of the conformational dependence of the geometry of peptide bond, the basic element of protein structures. Different peptide model systems have been studied...
