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  ARG-75   LYS-76  2.6 1.5 10.5 33.7 142.4 116.0 -21.4  LYS-76   MET-77  1.7 3.0 -23.6 46.8 66.3 59.3 -6.3  MET-77   LYS-78  2.8 3.7 -35.0 -3.0 72.7 21.1 16.0  LYS-78   ASP-79  3.8 1.6 -167.3 -48.4 9.2 51.5 -83.8  ASP-79   THR-80  5.5 3.6 -22.8 -48.0 71.9 86.4 10.7  THR-80   ASP-81  5.5 7.0 -166.6 73.4 113.7 95.0 127.6  ASP-81   SER-82  9.2 10.0 21.3 48.5 83.1 134.9 27.5  SER-82   GLU-83  12.3 13.1 67.4 2.4 91.1 85.3 18.5 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
