*1 The location of the fixed and moving segments indicated by the residue number assigned in the ligand-bound form. The background color of characters indicates the corresponding segment in the structure. The colored segments not described in the Table are: 1) a part of component in which the motion is small (< 1.0 A), or, 2) a part of a protomer of homodimers, for which a corresponding part of the other protomer is shown in the Table.
