sounds like the protein just diffuses. since you are using pbc, the
protein is solvated, given the dimensions of the box are larger than
those of the protein. The box you see after wrapping is generated by
wrapping molecules in such a way, that the individual molecules don't
get broken. This way, it may look like a part of the protein sticks
out of the box. Check the manual for the behavior of the wrapall
parameter. Simulate longer, and once it is about to move completely
out of the box, it will be wrapped back into the box. why should one
change the physics by fixing atoms just so it looks nice?
