More information available from the Warshel Center for Multiscale Simulations
Developed by Nobel Laureate Arieh Warshel, MOLARIS-XG is a specialized computational chemistry and molecular simulation software package that helps scientists model and predict how biomolecules behave, especially proteins, enzymes, and drug candidates.
The software is especially valued in:
- Drug discovery — predicting how strongly a drug binds to a target protein and estimating reaction energetics before expensive lab experiments.
- Enzyme research — studying catalytic mechanisms and mutation effects using Empirical Valence Bond (EVB) methods, one of the areas Arieh Warshel pioneered.
- Protein energetics — calculating pKa values, electrostatics, redox potentials, ligand binding energies, and conformational changes.
- QM/MM simulations — combining quantum mechanics and molecular mechanics to model chemical reactions inside biological systems.
- Coarse-grained simulations — allowing researchers to study larger biomolecular systems more efficiently than full atomistic simulations.
Benefits
- Relative to more general molecular dynamics packages, MOLARIS-XG has a strong focus on enzyme catalysis and electrostatic effects, which are critical in biochemical reactions.
- Integrates methods like EVB, PDLD, FEP, and LRA into one platform.
Applications
- Design better enzymes
- Predict mutation effects
- Optimize drug candidates
- Model ion channels and GPCRs
- Study reaction pathways that are difficult to observe experimentally
