Protein-protein interaction energies can be quite tricky with MM-PBSA. You
might want to look at our recent paper on this:

%A H. Gohlke
%A D.A. Case
%T Converging Free Energy Estimates: MM-PB(GB)SA Studies on the
Protein-Protein Complex Ras-Raf
%J J. Comput. Chem.
%V 25
%P 238-250
%D 2004

...hope this helps...dac
