I have a structure that I am trying to finish off, I have Zn ligated by four cys residues.
I use the linkR and define distances (the same link for each ZnS bond)
My issue is how to stop the structure moving to a square pyramid (consistent with distance restraints) rather than a tetrahedral geometry.
Can anyone help?
best
