[gmx-users] FAD containing protein

[Andrea Carotti]

Hi gmx-users,
    I'm trying to prepare the input file of a FAD containing protein.
My FAD is covalently bound to a CYS residue. I've seen in the thesis of
Anton Feenstra that he changed the resiudue and the atom type in a manner to
be recognized by the gromos force field..He changed the FAD in FMN+AMP with
the respective atom types.
Someone did the same? and in my case (with the bond with the cys) what I
should do?
Please someone guide me in the preparation (topology file...)
Thanks a lot
Andrea
