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  13.8 14.9 -6.1 -0.5 102.4 119.9 1.3  ALA-73   ARG-74  12.3 14.2 19.2 -69.9 96.5 83.6 -3.1  ARG-74   LYS-75  8.9 10.7 146.7 -96.8 160.8 124.4 -19.0  LYS-75   MET-76  8.9 7.5 162.2 -4.2 113.0 92.0 -27.2  MET-76   LYS-77  9.8 4.7 -124.6 -7.0 102.1 14.2 59.8  LYS-77   ASP-78  7.6 4.1 -11.4 33.3 57.2 52.1 -7.8  ASP-78   THR-79  4.5 0.9 166.6 -83.7 164.3 131.1 -63.4  THR-79   ASP-80  6.0 2.4 -158.9 26.5 83.9 39.2 78.8  ASP-80   SER-81  7.5 3.6 -157.1 -10.9 93.1 57.0 -31.2  SER-81   GLU-82  4.9 3.8 -145.8 -22.4 27.5 44.2 125.8  GLU-82   GLU-83  3.0 1.9 56.2 -25.5 135.2 126.2 -17.1 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
