Description

Molecular dynamics simulation trajectory and  for wild-type acylated alpha-Synuclein (Ac-AS) using the REST2 algorithm. The system was parameterised with the a99SB-disp force field published by Maxwell et al. The simulation was run for 25 nanoseconds using GROMACS on the Forschungszentrum Jülich JUWELS supercomputer. The reposited trajectory is the lowest temperature replica at 300 K from 32 replicas between 300-500 K.

This work was partially performed as part of the Helmholtz School for Data Science in Life, Earth and Energy (HDS-LEE) and received funding from the Helmholtz Association of German Research Centers.

The authors gratefully acknowledge the Gauss Centre for Supercomputing e.V. (www.gauss-centre.eu) for funding this project by providing computing time through the John von Neumann Institute for Computing (NIC) on the GCS Supercomputer JUWELS at Jülich Supercomputing Centre (JSC).
