Dear gromacs users,
I want to ask if is it possible to amke proton proton exchange
simulations by now and constant pH simulations in new versions of Gromacs.
Not sure what you mean, but probably not. See recent publications from
Lindahl group for what is possible.

Hi all,
Constant-pH MD simulations using an older version of gromacs (v. 3.2.1)
is possible:
http://dx.doi.org/10.1021/jp056456q
http://dx.doi.org/10.1529/biophysj.106.092445
http://dx.doi.org/10.1002/prot.21923
http://dx.doi.org/10.1021/ja808463e
http://dx.doi.org/10.1021/jp104753t
Unfortunately, newer versions (v. 4.x.x) do not allow the use of Freeze
Groups in NPT simulations, which is essential for the method to work. In
case this is "solved" in future releases, we will port the method to new
and faster gromacs versions.
Regards,
