Domain

Independent

*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.


Displacement and disorder

Component No.

RMSD*1

Displacement*2

Disorder-order transition*3

Disorder residue*4

Helix-Coil*5

1

1.2

*1 The root-mean-square displacement of a component of motion calculated for the domain motions.
*2 The mean displacement of a component of motion calculated for the local motions.
*3 Order-disorder transition: Whether the open form contains the disordered structure.
*4 The number of disordered residues.
*5 The number of residues exhibiting the alpha-helix to coil transition.


Crystal environment

Component No.

Open state*1

Crystal packing*2

1

Bound

Coupled

*1 Distinction between the open state and the closed state required for examining the influence of the crystal environment.
*2 Crystal packing: Whether the change in the crystal environment is coupled with the structural change.
