dear users, dear justin,
many many thanks for your fast reply.
I know that I can use any ff for which adequate parameters are set.
I calculated MD for different DNA protein complexes, but the problem is how to
simulate the non-protein inhibitor and DNA-protein covalently linked in one
complex, since the AMBER FF i used to use ius not parameterizes for such
cases as far as I know. It is exactly my problem, that i do not know how to
parameterise this particular case and would be glad if anyone can give me a
hint on how to do.
Has anyone an idea ? perhaps a more general ff to apply ?
thanks a million times

In theory, you could use any force field for which adequate parameters have
developed for both proteins and DNA. In terms of your ligand and how to treat
it, see here:
