2FXY solution structure of 55-72 segment of staphylococcal nuclease.
15 conformers structures with the lowest energy.
The helix-forming tendencies of the peptide fragment are investigated using
nuclear magnetic resonance (NMR) method.
See Thermal
motion of peptide (Proteopedia.org) and
foldit.fandom.com/wiki/Rotamer.
If the animation time step is much larger than time between collisions,
then the rotamer probability with energy Er is proportional to exp(-Er/kT).
I didn't find conformer's energies. Therefore all conformers are equally probable.
See fixed conformers too.
