Force field parameter and topology for zinc finger protein

Hi everybody,

I am trying to set up a system for zinc finger-DNA complex using
CHARMM force field. However, I didn't find any appropriate CHARMM
forcefield file for that. Is there any patch residue (as like as HEME
for hemoglobin) that defines the zinc finger moiety in CHARMM
forcefield. I have been getting tired to look for such residue in
Internet from last week. Can anyone help me in this regard?

Looking forward to hear from you.

Thanks in advance
