You can easily calculate an energy value for the protein (single point energy
calculation), but it's not a free energy and it's totally force field-dependent.
Proteins are generally (mostly) rigid during docking, so any change in the
energy is probably small.
If this is related to your previous posts about the energy value after
minimization, it's really not a useful quantity because the systems are simply
