CALCULATIONS OF COORDINATES OF NON-BONDING ATOMS
In a three-dimensional Cartesian coordinate system as shown in Fig. 5-14,
place the -atom at the origin, the N-atom on the negative y-axis, and the
C-atom in the y,z-plane.

Locations of protein backbone atoms.
Thus, the coordinates of these three atoms are:
N
(0,-1.47,0), and
C
(0,0.52,1.44).
