[gmx-users] zinc fingers

Search the literature for bonded model...I assume you try to simulate 
In that case, zinc is not important for direct binding interactions...so 
the bonded model is quite fine.
For parameters, there is also a bit literature, but if you are able to 
do QM, that would be the best way...
Nevertheless non-bonded and dummy atom method are also described in the 
literature, but didn't work for me.

If you try to model the system with the new OPLSAA-FF Parameters, please 
be aware of these ...they are still under development, and may lead to 
questionable results, altopugh the complex is stable.
