Bending Residue Dihedral Analysis

Residue i Residue i+1 Distance of hinge axis to residue i in conformer 1 (A) Distance of hinge axis to residue i in conformer 2 (A) Change in psi (i) (deg) Change in phi (i+1) (deg) Angle of psi(i) axis to hinge axis conformer 1 (deg) Angle of psi(i) axis to hinge axis conformer 2 (deg) Percentage Progress  ILE-65   LYS-66  2.9 2.4 15.7 -18.4 31.4 38.1 2.1  LYS-66   CYS-67  3.4 2.4 -4.9 83.1 139.1 141.3 62.0  CYS-67   LYS-68  1.3 0.4 39.2 -18.7 46.0 35.6 11.5  LYS-68   ILE-69  2.5 2.1 6.0 -6.9 28.2 39.4 -11.3 Graph shows rotational transition at bending residues and can be used to identify hinge bending residues. Probably only informative for interdomain rotations greater than 20 degrees
