Category Description

               Data items in the ATOM_SITES_ALT category record details
               about the structural ensembles that should be generated from
               atom sites or groups of atom sites that are modelled in
               alternative conformations in this data block.

    ; Atom sites with the alternative ID set to null are not
      modeled in alternative conformations
    ;
     1
    ; Atom sites with the alternative ID set to 1 have been
      modeled in alternative conformations with respect to atom
      sites marked with alternative ID 2. The conformations of
      amino-acid side chains and solvent atoms with alternative
      ID set to 1 correlate with the conformation of the
      inhibitor marked with alternative ID 1. They have been
      given an occupancy of 0.58 to match the occupancy assigned
      to the inhibitor.
    ;
     2
    ; Atom sites with the alternative ID set to 2 have been
      modeled in alternative conformations with respect to atom
      sites marked with alternative ID 1. The conformations of
      amino-acid side chains and solvent atoms with alternative
      ID set to 2 correlate with the conformation of the
      inhibitor marked with alternative ID 2. They have been
      given an occupancy of 0.42 to match the occupancy assigned
      to the inhibitor.
    ;
     3
    ; Atom sites with the alternative ID set to 3 have been
      modeled in alternative conformations with respect to
      atoms marked with alternative ID 4. The conformations of
      amino-acid side chains and solvent atoms with alternative
      ID set to 3 do not correlate with the conformation of the
      inhibitor. These atom sites have arbitrarily been given
      an occupancy of 0.50.
    ;
     4
    ; Atom sites with the alternative ID set to 4 have been
      modeled in alternative conformations with respect to
      atoms marked with alternative ID 3. The conformations of
      amino-acid side chains and solvent atoms with alternative
      ID set to 4 do not correlate with the conformation of the
      inhibitor. These atom sites have arbitrarily been given
      an occupancy of 0.50.
