QMrebind: Quantum Mechanical reparametrization at the receptor-ligand binding site

Release:

0.4.0

Date:

Dec 15, 2023

Molecular mechanics (MM) forcefields (FF) seek to approximate the potential energy surface (PES) of molecules in regions of phase space likely to be sampled in a realistic situation (for example: near equilibrium, in a biological context, etc.) While the FFs of common features, such as amino acids, are quite optimized, the parametrization of small molecules can be difficult and prone to errors. The QMrebind software automates the generation of parameters for small molecules in a context of interest - within the binding site, for instance. Therefore, a highly accurate PES is generated for the region of phase space where the ligand is in the bound state. The resulting parameters may be then used as input to subsequent calculations, such as SEEKR2.
