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  LYS-338   ALA-339  1.6 1.5 5.0 -47.2 63.7 76.4 -66.5  ALA-339   LYS-340  4.3 4.4 32.1 -1.0 61.6 31.4 80.8  LYS-340   GLY-341  6.9 6.7 -9.8 53.5 153.4 133.6 135.8  GLY-341   GLN-342  8.3 7.5 -25.0 12.4 138.1 143.5 -30.9  GLN-342   PRO-343  6.9 6.6 -20.3 22.7 102.0 105.8 -60.1 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
