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  ASP-78   THR-79  5.1 5.4 -123.5 47.4 36.3 32.9 79.9  THR-79   ASP-80  5.6 7.1 -165.2 9.4 53.3 38.1 136.0  ASP-80   SER-81  3.8 4.3 23.0 -80.9 130.6 111.7 -351.0  SER-81   GLU-82  1.4 2.5 143.0 -21.9 158.5 144.5 324.3  GLU-82   GLU-83  2.0 0.8 44.0 -8.9 140.6 144.6 -45.2 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
