    ; 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.
