Published macromolecular structure data files ([[Atomic coordinate files]], often in the [[PDB file format]]) contain the [[Asymmetric Unit]], which may be identical with the biological unit, or only a portion of it, or may contain multiple biological units. When publishing a macromolecular structure, the authors may elect to specify the biological unit. In the [[PDB file format]], this is done in REMARK 350. | Published macromolecular structure data files ([[Atomic coordinate files]], often in the [[PDB file format]]) contain the [[Asymmetric Unit]], which may be identical with the biological unit, or only a portion of it, or may contain multiple biological units.
