摘要: The differences between two databases describing the polypeptide main chain in terms of charge-density parameters, directly usable protein structure refinements, are discussed. These contain averaged multipole populations peptide pseudo-atoms obtained from refinement against theoretical simulated data and high-resolution experimental on small or amino acid molecules. discrepancy becomes apparent when electrostatic properties calculated.
