abstract = {Enhanced sampling methods can predict free-energy
landscapes associated with protein/ligand binding,
characterizing the involved intermolecular interactions in a
precise way. However, these in silico approaches can be
challenged by induced-fit effects. Here, we present a
variant of volume-based metadynamics tailored to tackle this
problem in a general and efficient way. The validity of the
approach is established by applying it to substrate/enzyme
complexes of pharmacological relevance: mono-ADP-ribose
(ADPr) in complex with mono-ADP-ribosylation hydrolases
(MacroD1 and MacroD2), where induced-fit phenomena are known
to be significant. The calculated binding free energies are
consistent with experiments, with an absolute error smaller
than 0.5 kcal/mol. Our simulations reveal that in all
circumstances, the active loops, delimiting the boundaries
of the binding site, undergo significant conformation
rearrangements upon ligand binding. The calculations further
provide, for the first time, the molecular basis of ADPr
specificity and the relative changes in its experimental
binding affinity on passing from MacroD1 to MacroD2 and all
its mutants. Our study paves the way to the quantitative
description of induced-fit events in molecular recognition.},
