[Chimera-users] adding metal ions

[Carlo Zambonelli]

I have a pdb file with the coordinates of an apo-enzyme. I know Fe3+ and 
Zn2+ are essential for catalysis; I also know some of the residues 
involved in coordination of Fe3+ and Zn2+. Can I position 2 ions in the 
structure so that they are correctly oriented relative to the 
coordinating residues? My ultimate goal is to create a PDF file 
containing also the metal ions.
Thanks,
Carlo
