Dear Prateeksha,
You need to generate a new residue for the protonated Adenosine. Once you have
the force field files for this residue, you can use it along with the usual ff
to carry out your simulations. You can find a detailed description of how to
generate "prepin" and "frcmod" files for a modified nucleoside in the following
article:
"Aduri, R.et al., J. Chem. Theory Comput., vol. 3, 1464 - 1475, 2007"
I hope this helps.
Sincerely
Raviprasad Aduri
