abstract = {Intrinsically disordered proteins are essential for
biological processes such as cell signalling, but are also
associated to devastating diseases including Alzheimer's
disease, Parkinson's disease or type II diabetes. Because of
their lack of a stable three-dimensional structure,
molecular dynamics simulations are often used to obtain
atomistic details that cannot be observed experimentally.
The applicability of molecular dynamics simulations depends
on the accuracy of the force field chosen to represent the
underlying free energy surface of the system. Here, we use
replica exchange molecular dynamics simulations to test five
modern force fields, OPLS, AMBER99SB, AMBER99SB*ILDN,
AMBER99SBILDN-NMR and CHARMM22*, in their ability to model
Aβ42, an intrinsically disordered peptide associated with
Alzheimer's disease, and compare our results to nuclear
magnetic resonance (NMR) experimental data. We observe that
all force fields except AMBER99SBILDN-NMR successfully
reproduce local NMR observables, with CHARMM22* being
slightly better than the other force fields.},
