[gmx-users] Problem wih Fe-S cluster

[Tsjerk Wassenaar]

Hi Subarna,

If you just want to retain the structure of the cluster it doesn't
matter too much. It may be good to average values from different
structures, though. HOWEVER, an FeS cluster is a catalytic site, which
probably has fancy electronic properties, which may well affect the
behaviour of the surrounding protein. If you are interested in the
protein dynamics, you want to describe it properly. Doing so requires
proper parameterization, ergo performing quantum mechanical
calculations with validation against experimental data, ergo doing a
lot of work. This is not something for a lazy Sunday afternoon!

Cheers,

Tsjerk
