Consider the bond distance between
and
-atoms to be 1.53 A. Then
a similar calculation gives the coordinates ofthe
-atom as:
The coordinates of other atoms will depend on the angles. Fig. 5-14
shows the protein backbone structure in a stretched out configuration
corresponding to in the old convention. Thus, coordinates of various
atoms will first be given in the old convention, and then repeated in the new
convention. Since
and
the expressions in the old and new conventions differ by a sign change,
whenever or is involved.
With the use of rotation matrix discussed in the Appendix, those depend on
the angle are:
