modeling zinc binding site

Hi,

I wish to model zinc binding site.

I have a homology model of a protein which binds zinc. The model is
based on the homolog which does not have the binding site for zinc. I
have identified potential aminoacid residues engaged in zinc binding.
However, the geometry of the zinc binding site in my homology model is
far from the geometry allowing for binding zinc -the structural elements
containing zinc binding residues must reorganize to allow for proper
geometry.

Thus I need to refine the model to predict the structure of a zinc
binding site.

Is it possible to model this site using namd? Coud you propose me a
proper approach for doing this? I cannot find if someone has done
similar things. Maybe I should specify constraints for to place zinc
binding groups around zinc ion or use steered molecular dynamics?

I appreciate any help,

Jan Kosinski
