    ; The inhibitor binds to the enzyme in two alternative
      orientations. The two orientations have been assigned
      alternative IDs *1* and *2*.
    ;
      2
    ; Side chains of these residues adopt alternative
      orientations that correlate with the alternative
      orientations of the inhibitor.
      Side chains with alternative ID *1* and occupancy 0.58
      correlate with inhibitor orientation *1*.
      Side chains with alternative ID *2* and occupancy 0.42
      correlate with inhibitor orientation *2*.

    ; The positions of these water molecules correlate with
      the alternative orientations of the inhibitor.
      Water molecules with alternative ID *1* and occupancy 0.58
      correlate with inhibitor orientation *1*.
      Water molecules with alternative ID *2* and occupancy 0.42
      correlate with inhibitor orientation *2*.

    ; Side chains of these residues adopt alternative
      orientations that do not correlate with the alternative
      orientation of the inhibitor.

    ; The positions of these water molecules correlate with
      alternative orientations of amino-acid side chains that
      do not correlate with alternative orientations of the
      inhibitor.
