An alternative identifier for _atom_site.label_asym_id that may be provided by an author in order to match the identification used in the publication that describes the structure.
An alternative identifier for _atom_site.label_atom_id that may be provided by an author in order to match the identification used in the publication that describes the structure.

An alternative identifier for _atom_site.label_seq_id that may be provided by an author in order to match the identification used in the publication that describes the structure.
Note that this is not necessarily a number, that the values do not have to be positive, and that the value does not have to correspond to the value of _atom_site.label_seq_id. The value of _atom_site.label_seq_id is required to be a sequential list of positive integers.
The author may assign values to _atom_site.auth_seq_id in any desired way. For instance, the values may be used to relate this structure to a numbering scheme in a homologous structure, including sequence gaps or insertion codes. Alternatively, a scheme may be used for a truncated polymer that maintains the numbering scheme of the full length polymer. In all cases, the scheme used here must match the scheme used in the publication that describes the structure.
The group of atoms to which the atom site belongs. This data item is provided for compatibility with the original Protein Data Bank format, and only for that purpose.
The value of _atom_site.id must uniquely identify a record in the ATOM_SITE list.
Note that this item need not be a number; it can be any unique identifier.
This data item was introduced to provide compatibility between small-molecule and macromolecular CIFs. In a small-molecule CIF, _atom_site_label is the identifier for the atom. In a macromolecular CIF, the atom identifier is the aggregate of _atom_site.label_alt_id, _atom_site.label_asym_id, _atom_site.label_atom_id, _atom_site.label_comp_id and _atom_site.label_seq_id. For the two types of files to be compatible, a formal identifier for the category had to be introduced that was independent of the different modes of identifying the atoms. For compatibility with older CIFs, _atom_site_label is aliased to _atom_site.id.
In general, this aggregate identifier does not uniquely identify an atom site as for non-polymers _atom_site.label_seq_id is '.'.

Data items in the DATABASE_2 category record details about the database identifiers of the data block.
These data items are assigned by database managers and should only appear in a data block if they originate from that source.
The name of this category, DATABASE_2, arose because the category name DATABASE was already in use in the core CIF dictionary, but was used differently from the way it needed to be used in the mmCIF dictionary. Since CIF data names cannot be changed once they have been adopted, a new category had to be created.

Data items in the ENTITY category record details (such as chemical composition, name and source) about the molecular entities that are present in the crystallographic structure.
Items in the various ENTITY subcategories provide a full chemical description of these molecular entities.
Entities are of three types: polymer, non-polymer and water. Note that the water category includes only water; ordered solvent such as sulfate ion or acetone would be described as individual non-polymer entities.
The ENTITY category is specific to macromolecular CIF applications and replaces the function of the CHEMICAL category in the CIF core.
It is important to remember that the ENTITY data are not the result of the crystallographic experiment; those results are represented by the ATOM_SITE data items. ENTITY data items describe the chemistry of the molecules under investigation and can most usefully be thought of as the ideal groups to which the structure is restrained or constrained during refinement.
It is also important to remember that entities do not correspond directly to the enumeration of the contents of the asymmetric unit. Entities are described only once, even in those structures that contain multiple observations of an entity. The STRUCT_ASYM data items, which reference the entity list, describe and label the contents of the asymmetric unit.

If there is any doubt that the equivalent positions can be uniquely deduced from this symbol, specify the _symmetry_equiv.pos_as_xyz or _symmetry.space_group_name_Hall data items as well. Leave spaces between symbols referring to different axes.
Space-group symbol as described by Hall (1981). This symbol gives the space-group setting explicitly. Leave spaces between the separate components of the symbol.
