abstract = {RNA/protein interactions play crucial roles in controlling
gene expression. They are becoming important targets for
pharmaceutical applications. Due to RNA flexibility and to
the strength of electrostatic interactions, standard docking
methods are insufficient. We here present a computational
method which allows studying the binding of RNA molecules
and charged peptides with atomistic, explicit-solvent
molecular dynamics. In our method, a suitable estimate of
the electrostatic interaction is used as an order parameter
(collective variable) which is then accelerated using
bidirectional pulling simulations. Since the electrostatic
interaction is only used to enhance the sampling, the
approximations used to compute it do not affect the final
accuracy. The method is employed to characterize the binding
of TAR RNA from HIV-1 and a small cyclic peptide. Our
simulation protocol allows blindly predicting the binding
pocket and pose as well as the binding affinity. The method
is general and could be applied to study other
electrostatics-driven binding events.},
