Sampling macromolecular transitions

Sampling macromolecular transitions

While equilibrium MD is considered the most robust approach to simulating macromolecular conformational changes, conformational transitions are rare events that take place on much faster timescales than the waiting times spent in metastable equilibrium states. Equilibrium simulations thus spend relatively little time sampling actual transition events. Fast transition path sampling methods seek to mitigate the rare event sampling problem, though the full extent to which biased or coarse-grained approaches can replicate physical ensembles of transitions is unknown.
