Structures in the reaction coordinate (500 fs) for native light (A), native heavy (B), F159Y light (C), and F159Y heavy (D) PNPs from the perspective of the O5′–O4′ distance. Negative values of BB – BF are reactant states, and positive values of BB – BF are product states. Transition states are near zero on the abscissa scale. Contour lines join points with equal population densities. Adapted from ref 33. Copyright 2017 National Academy of Sciences.
