Before the final optimization you mention, is there bad overlap between the
protein and the ligand?
It is not clear why you are removing the ligand, doing a Gaussian
optimization, and putting the ligand back in. Also, it is unclear from your
email what you mean when you say "after that I add to protein": did you add
the entire heme-O2 ligand or just the O2 itself back to the protein? I would
recommend avoiding the Gaussian optimization, and just using the original
coordinates in the PDB file.
