Hi 
 
I am trying to find electrostatic potential values of pairs of atoms at interface (protein - protein interaction).

Could anyone please guide me how do i compute these electrostatic potential values for pair of atoms/amino acids?
Can APBS help me out (as i understand it gives electrostatic potential values for protein-solvent interaction)

 
Looking forward for a positive response.
 
Thanks and regards
