Ions to model
Some proteins have ions important for structure/ catalysis. In order to preserve their original function, it is recommended to keep them in the exact same position during FuncLib's simulations.
In order to use this option, make sure the ion's coordinates are specified in the protein structure- either in the self-uploaded PDB file or in the Protein Data Bank version of the structure.


Please provide both the residue number and the chain it is located on.
