Simulated Solute Tempering 2: An Efficient and Practical Approach to Protein Conformational Sampling and Binding Events Molecular dynamics (MD) simulations are powerful tools for studying the movement and interactions of molecules, but they can be computationally expensive, especially for large biomolecules like proteins. This is problematic because accurately simulating the motions of these molecules is key to understanding their functions. Enhanced sampling methods, such as Simulated Tempering (ST), temperature Replica Exchange Molecular Dynamics (REMD), and Replica Exchange with Solute Tempering (REST and REST2), have been developed to overcome this challenge by improving the efficiency of MD simulations. This work presents a new enhanced sampling method called Simulated Solute Tempering 2 (SST2) that builds upon the strengths of ST and REST2. SST2 selectively scales the interactions inside a biomolecule and with its surrounding environment, effectively accelerating the exploration of its different structural states and their stabilities at various temperatures. SST2 is tested on three different systems (chignolin CLN025, Trp-Cage, and a protein–peptide complex, p97/PNGase) and is found to achieve comparable or superior sampling efficiency to ST, SST1, and REST2 while requiring fewer temperature rungs. Notably, SST2 is particularly well-suited for investigating large biomolecular systems, making it a valuable tool for studying a wide range of biomolecular processes, from protein folding to ligand binding.

🎉 Thrilled to announce that our paper "Simulated Solute Tempering 2 (SST2): An Efficient and Practical Approach to Protein Conformational Sampling and Binding Events" is now published in JCTC! pubs.acs.org/doi/full/10....

I got fooled by AI-for-science hype—here's what it taught me I used AI in my plasma physics research and it didn’t go the way I expected.

The last version of SST2 manuscript is out. As recommended, we have performed additional simulations using the REST2 and SST1. SST2 offers highly competitive sampling efficiency, with significant advantages in terms of computational cost and ease of implementation compared to both REST2 and SST1.

We are happy to announce the release of MassiveFold 1.5.0.

It is now possible to add post-translational modifications and to run ligand screening with AlphaFold3!

New preprint! @tatilab.bsky.social imaged the honeybee GABAA RDL receptor. ~10% of insecticides target insect GABAA receptors. She found a new allosteric modulation pocket, a PIP2 site, a closed avermectin-bound conformation, and maybe an unusual desensitized state.

It is indeed striking how much AF3-based methods struggle to generalize to novel protein-ligand interfaces. It is also interesting that there remains a meaningful delta between AF3 and other reproductions at the most difficult generalization task (~25% vs ~13% success rate, so roughly double).
