PDB Fixer

This site provides facilities to mutate and change side-chains of a PDB file automatically.

This will also allow for repairing missing side-chains in a PDB file, constructing polar hydrogen atoms and assigning partial charges for electrostatic calculations.

Warning: This suite of programs does not work well with multimers.
At the moment the only way around this is to decompose the oligomer in single monomers, repair them individually and concatenate the results to re-generate the repaired oligomer...
