Please excuse my lack of chemistry, but is the D-isomer
chemically different from the L? If they are chemically
the same, all you should need is to load a pdb with the
D-isomer - as long as atoms are not missing for the template
to supply from its L form, things would be ok in that simulations
could be run. In this case, the only reason for developing
an L-isomer template would be to have different atomic
charges if L is not a mirror of D, or for convenience in
placing missing atoms.
