Item Description

The z component of the coordinates for this atom in this component specified as orthogonal angstroms. The choice of reference axis frame for the coordinates is arbitrary. The set of coordinates input for the entity here is intended to correspond to the atomic model used to generate restraints for structure refinement, not to atom sites in the ATOM_SITE list.
