It depends on what experiments you are trying to compare to. Actual proteins
in experiments would almost never have these capping groups. If there is
really something there that is not visible in the X-ray density, I think
most people would just simulate residues 100-500, with the end residues either
charged or uncharged. If it makes a difference which choice you make, then
you probably have an ill-defined simulation problem anyway.
