If the zinc bridges the two proteins, you essentially have a covalent
connection, and it will be hard to get binding energies. Think carefully
about what reactions you are studying, what experimental data you might
have, and what you would do with the result.

Look at at the "radiopt" option, which will use the radii in the prmtop
file.
