first off, I hope you don't really have a mirror image of your protein
in your simulation. You shouldn't mix L- and D-amino acids.
Since your water box is infinitely repeated for the purpose of the
simulation, it probably doesn't matter that your proteins sticks out.
It reenters the box on the other side, and all is good. If you see
interactions between the master copy of your model and models in
equivalent positions in adjacent cells, your water box might be too
small. Start with something bigger.
