Dear Netters, I would like to know whether programs exist (either free or commercial) which perform molecular dynamics with the aim of simulating protein-protein recognition. Should this be brownian dynamics? Protocols for performing such studies with an "ordinary" molecular dynamics program (e.g. AMBER, CHARMM...) are welcome as well Thanks to all!
