The answer depends entirely on your system. What is your atom selection
within the protein and what are their bfactors (or whatever value you are
using)? Note that the applied force constant is constraintScaling*bfactor.
For early stage equilibration it would not be unreasonable to apply
restraints to all heavy atoms.
