| Determination of torsion angles between adjacent residues
using solid-state NMR frequencies |
This is a backbone only model. Constant peptide plane
geometry was assumed. Torsion angles phi and psi were
allowed to vary within 10-20 degrees relative to phi=-65,
psi=-40. Radial and angular positioning of subunits in a
manner similar to and in comparison with structure 1PJF,
which involved minimization against published neutron
diffraction distance constraints and energy minimization
with sidechains using the program SCWRL. |
