abstract = {Metal ions are both ubiquitous to and crucial in biology.
In classical simulations, they are typically described as
simple van der Waals spheres, making it difficult to provide
reliable force field descriptions for them. An alternative
is given by nonbonded dummy models, in which the central
metal atom is surrounded by dummy particles that each carry
a partial charge. While such dummy models already exist for
other metal ions, none is available yet for Cu2+ because of
the challenge to reproduce the Jahn–Teller distortion.
This challenge is addressed in the current study, where, for
the first time, a dummy model including a Jahn–Teller
effect is developed for Cu2+. We successfully validate its
usefulness by studying metal binding in two biological
systems: the amyloid-β peptide and the mixed-metal enzyme
superoxide dismutase. We believe that our parameters will be
of significant value for the computational study of
Cu2+-dependent biological systems using classical models.},
