I will really appreciate any help of suggestions.I am doing simulation
of six monomers of identical helical peptide. the experiment literature
say that the peptides in a aqueous solution should form a hexamer. so i
have done simulations for the six peptides under normal conditions with
T of 300k and the result are two trimer that are perpendicular with each
other.
I don't know that to do to get the monomers rearrange and form a
heaxamer instead of two trimers.
You haven't said how long your simulations are, but such processes are likely to
take quite some time. You may need extensive simulation or some fortuitous
starting configuration to actually produce this behavior. If the literature
measures the kinetics of such a process, then you have a baseline for what you
might expect; keep in mind that atomistic MD simulations are generally only
feasible on the submicrosecond time frame.
