Dear Sweta,
You indicated that you used of water box with an 12 angstrom buffer. That
means that initially the protein is 24 angstroms away from its mirror image.

Imagine there is no deformation in the structure of the protein. Even if the
protein is protruding out of the water box it would be still 24 angstroms
away from its mirror image (because the mirror image makes the same move).
However if the deformation in the structre is so high that the 24 angstrom
gap is getting smaller (I don' know what your protein is) they may interact.
Can you send me a screenshot where the protein in the simulation box and the
mirror image have come close to each other .
Best,
Mert
