The current versions of implicit solvation models that work together
with mm_pbsa (GB in sander or delphi II) don't allow a
more-than-two-media world (i.e. one explicit molecule/complex inside a
continuum region). (The latest version of delphi does though, but I have
no experience with it in the context of mm_pbsa.)
If your ligand binding site is well located within the protein (i.e.
distant from the membrane region), it might be worth trying to use the
current setup.
