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  SER-79   LEU-80  6.2 6.0 -17.6 13.7 167.6 165.5 -20.6  LEU-80   PRO-81  5.6 5.2 -5.0 -14.5 117.3 123.7 -88.2  PRO-81   GLY-82  7.5 6.9 2.1 36.9 52.9 44.8 300.3  GLY-82   VAL-83  10.3 9.4 -41.1 21.6 74.4 71.7 46.2  VAL-83   ASP-84  10.5 11.2 -29.4 30.9 94.1 103.9 13.4  ASP-84   VAL-85  14.2 14.6 -61.1 47.5 155.1 161.5 -126.2  VAL-85   SER-86  14.3 14.5 3.8 -0.7 49.4 47.6 38.3 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
