Hi,
Personally, I rather add ions up to physiological salt concentration,
in addition to counterions, which makes the equilibration quicker,
also accounts for the presence of both positive and negative charges
on the protein surface and, probably mainly due to the latter, has a
stabilizing effect on the proteins in simulation.
Not meaning to be cynical but where does this wisdom come from? It makes
sense and most people will agree, but are you aware of any systematic tests?
