Overview

Adjustments to absolute binding free energy methods improve convergence in protein-ligand interactions, suggesting enhanced reliability.

Key Points

  • Optimizations led to improved stability and reliability in absolute binding free energy calculations.
  • The new algorithm for protein-ligand pose restraints reduced numerical instabilities and improved convergence.
  • Rearranging interaction scaling resulted in more precise calculations of binding affinities.
  • Benchmarking on four systems showed up to a 0.23 kcal/mol improvement in error reduction of free energy results.
