The highly refined 1.26 A structure (R = 0.15) of phosphate-free bovine pancreatic ribonuclease A was modeled with 13 residues having discrete multiple conformations of side chains. These residues are widely distributed over the protein surface, but only one of them, Lys 61, is involved in crystal p
Although the conformations of two linked peptide units both with glycyl and alanyl residues have been extensively studied,'-$ no systematic investigation of the energies of conformations of two linked peptide units with side chains beyond the CB atom and a comparison with the available crystallograp
