Hi I got the protein crystal structures from the PDB file. There are only residues and water in the PDB files.
Why does the protein carry charges? Why aren't they electrically neutral? What are their intrinsic counter ions ? Thank you Lin _______________________________________________ gmx-users mailing list gmx-users@gromacs.org http://www.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
