I am writing to ask for some general advice on an RNA project.
We have an RNA with a single protonated adenine and have solved the
NMR structure. My next goal
is to use AMBER to refine (or even re-calculate) this structure taking
into account the behaviour of the protonated adenine. Do I need to
create a special residue or library and if so is there a simple way to
do this? What then is the best way to calculate the structure at a
constant solution pH to maintain adenine
protonation and see the effect on the structure?
Further down the line I would like to simulate the system under
different pH conditions to see if any structural transition can be
detected. Is this a reasonable or feasible project to approach using
AMBER and where should I start?
I realize that these are very general questions but any advice would
be appreciated.
Thanks,
Michael.
