refmac-dictionary - 5.41-3 main

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.
