Name:
'symmetry'

Description:

   Data items in the SYMMETRY category record details about the
   space-group symmetry.

Example:

Example 1 - based on PDB entry 5HVP and laboratory records for the structure corresponding to PDB entry 5HVP. 
 
    _symmetry.entry_id                     '5HVP'
    _symmetry.cell_setting                 orthorhombic
    _symmetry.Int_Tables_number            18
    _symmetry.space_group_name_H-M         'P 21 21 2'
