dictionary for macromolecular refinement and model building

Dictionary of ligands and constituent blocks (e.g. amino acids, nucleic acids, sugars) contains necessary stereochemical information (e.g. bond lengths, angles, torsion angles) about small molecules used in refinement and model building. Values in the dictionary are for an abstract form of monomers, i.e there is no conformational/configurational or environment dependence.
