Festival of Biologics, Basel, Switzerland

October 10, 2023 to October 12, 2023

Schrödinger is excited to be participating in the Festival of Biologics conference taking place on October 10th-12th in Basel, Switzerland. Join us for a presentation by Esam Abualrous, Senior Scientist II at Schrödinger, titled “Enabling Prediction of Protein-Protein Binding Affinities Using FEP+”. 

Speaker: Esam Abualrous, Senior Scientist II
Physics-based free energy perturbation (FEP) calculations provide accurate energetics while allowing conformational flexibility by using explicit solvent molecular dynamics (MD) simulations with a state-of-the-art force field. The accuracy and efficiency of these calculations can be improved through enhanced sampling protocols for mutating residue and nearby waters, effective handling of proline and charged amino acids, and automated parameterization of non-canonical amino acids. FEP+ and our new constant-pH molecular dynamics (CpHMD) implementation can account for protonation and tautomeric state changes, both upon binding/folding and at different pH values. Our approach was recently demonstrated in a real-world collaboration, where it was able to reduce cost and accelerate the development process significantly.
