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 2.7 14.8 -8.6 37.5 41.6 6.6  LYS-66   CYS-67  4.1 2.9 -6.1 85.5 147.5 148.5 62.6  CYS-67   LYS-68  2.0 0.9 53.8 -17.1 50.1 47.1 25.3  LYS-68   ILE-69  4.2 3.5 -62.6 61.0 157.9 160.1 -10.8  ILE-69   GLU-70  2.0 1.8 5.5 -18.4 63.3 53.1 -3.6 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
