Hi, There are methodological difficulties in simulating multivalent ions together with proteins. Check the mailing list for a discussion and reference. This is not an issue of Gromacs but of dealing with protein-ion interactions using a classical non-polarisable force field. Check the literature.

Now I want to see whether that region binds to zinc ions or not and what is the effect of ion binding to the topology of the protein .. Can this be done using gromacs and how ??
