XmlmmCIF equivalent: chem_comp_chir_atom Data items in the CHEM_COMP_CHIR_ATOM category enumerate the atoms bonded to a chiral atom within a chemical component. XmlmmCIF equivalent: chem_comp_chir_atom/dev The estimated standard deviation of the position of this atom from the plane defined by all of the atoms in the plane. XmlmmCIF equivalent: chem_comp_chir_atom/chir_id This data item is a pointer to _chem_comp_chir.id in the CHEM_COMP_CHIR category. XmlmmCIF equivalent: chem_comp_chir_atom/atom_id The id of an atom bonded to the chiral atom. This data item is a pointer to _chem_comp_atom.atom_id in the CHEM_COMP_ATOM category. XmlmmCIF equivalent: chem_comp_chir_atom/comp_id This data item is a pointer to _chem_comp.id in the CHEM_COMP category.
