Data from: QMrebind: Incorporating quantum mechanical force field reparameterization at the ligand binding site for improved drug-target kinetics through milestoning simulations Ojha, Anupam A.; Author; https://orcid.org/0000-0001-6588-3092; Votapka, Lane W.; Contributor; https://orcid.org/0000-0002-0865-5867; Amaro, Rommie E.; Corresponding Author; https://orcid.org/0000-0002-9275-9553 0000-0003-1023-6124 The data set contains the files necessary to recalculate/reproduce the unbinding rates of ligands for the model host-guest systems and Hsp90-inhibitor complexes in the paper "QMrebind: Incorporating quantum mechanical force field reparameterization at the ligand binding site for improved drug-target kinetics through milestoning simulations." The data contains the Simulation Enabled Estimation of Kinetic Rates (SEEKR) and QMrebind-reparameterized SEEKR2 simulations for model host-guest systems and Hsp90-inhibitor complexes with instructions to compute the drug-target unbinding rates in these complexes.

Cambridge: Cambridge Open Engage; 2023, Version 1. https://doi.org/10.26434/chemrxiv-2023-s4n3r Instructions: To recalculate/reproduce the unbinding rates of ligands for the model host-guest systems and Hsp90-inhibitor complexes, please follow the given steps: 1. Make sure the SEEKR2 program is installed by following the steps given on GitHub: (a) https://github.com/seekrcentral/seekr2 (b) https://github.com/seekrcentral/seekr2\_openmm\_plugin 2. Create a SEEKR2 conda environment and activate it. 3. Untar the downloaded JAK data and place it in any given directory. 4. Go to the qmrebind\_data directory and find further instructions in the "instructions.txt" files in the host\_guest\_complexes and hsp90\_inhibitor\_complexes folders.
