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  MET-72   ALA-73  0.9 1.0 1.5 -4.1 149.5 148.5 -0.4  ALA-73   ARG-74  1.9 2.1 20.3 -13.0 131.5 131.7 1.4  ARG-74   LYS-75  3.4 4.3 -36.5 -23.1 74.7 46.5 14.2  MET-76   LYS-77  2.2 5.2 -143.5 -24.1 87.2 59.1 -79.6  SER-81   GLU-82  9.7 8.4 -118.6 56.8 83.9 76.9 -20.9  GLU-82   GLU-83  12.1 11.3 -40.2 22.2 101.0 107.4 -1.5  GLU-83   GLU-84  15.3 14.0 -7.5 -8.5 172.6 165.2 205.9 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
