Indeed, though one should pay close attention to the parameter penalties in the
adenine nucleotide portion of the molecule, as that part is covered by standard
CHARMM. Any deviations should be investigated, though they will probably be
small and therefore unimportant. Most of the necessary functional groups for
FAD are already in CHARMM, just not parametrized explicitly, so I suspect a
CGenFF topology to be of pretty high quality since the analogy will be strong.
