Dear Krisztina,

Two enantiomers have the same charge values (if the
'exact/corresponding' orientations are involved in MEP computation).

Yes, although putting a D-amino-acid in the middle of L-amino-acids
leads to diastereoisomers, which would have different charge values
and identical atom types.
If I remember Simmerling's group has published a work about charge
values and diastereoisomers. I am sure people in this list know this
reference...

Simply transform the x coordinates into -x.
