📣 ❗2nd Preprint of the Summer ❗ 📣 "Kinase inhibitors can change protonation or tautomeric state upon binding." LInk: doi.org/10.64898/202... We find that kinase-inhibitors can change in net-charge and tautomer state upon binding (from solution-state to kinase-bound), affecting med-chem choices!

🧪⚛️ Our paper is finally published in Phys Rev Research! doi.org/10.1103/cnfz... Can cells make decisions using equilibrium physical principles, without resorting to irreversible, energy-consuming signaling cascades? We say yes, with the help of self-assembling membrane proteins! 🧵(1/7)

Plot of fractional response vs receptor concentration, comparing three different "passive sensing mechanisms": direct binding from solution, membrane-assisted binding, and membrane self-assembly.

Why is it so difficult to predict accurate mutational effects on protein stability? We explored the contribution from changes in native state configurational entropy in this paper, which also happens to be the last from my PhD. A short thread of why this matters. 1/n doi.org/10.48550/arX...

We introduce ConforNets, a mechanism for conformational control in AlphaFold3 models - SoTA at producing diverse conformations on every multistate benchmark (N=104) - Novel capability: transfer state from one protein to another Outperforms BioEmu, ConforMix and AFsample3 🧵1/8

Third preprint of the year is from @julianstreit.bsky.social who, with our collaborators at Peptone, show that multithermal On-the-fly Probability Enhanced Sampling (OPES) enables efficient generation of atomistic ensembles for disordered peptides and proteins 🍝 www.biorxiv.org/content/10.6...

Figure 1 from the paper: Sampling disordered peptides and proteins with OPES multithermal simulations. a. Representative multithermal molecular dynamics simulation showing fluctuations in potential energy (left) as the system explores a broad temperature range (colour scale). The right panel shows the relative effective sample size, N_eff, sampled across temperatures, demonstrating relatively uniform ensemble coverage. The black horizontal line represents the expected sample size in an equivalent temperature replica exchange setup (1 / M, where M is the number of temperatures). B. Structures of the most helical conformations sampled during multithermal simulations for four systems of increasing complexity: the helical control peptide (AAQAA)3, the ACTR20-60 fragment, full-length ACTR, and HTTex1 with 16 glutamine repeats (16Q). c. Free-energy landscapes plotted as a function of helicity (see Methods) and radius of gyration for the ACTR20-60 fragment, full-length ACTR and HTTex1 16Q at 300 K.

The work by @danialv.bsky.social is now out in @pnas.org with a few changes after peer-review. Have a look if you are interested in lipid transport by bridge lipid transfer proteins (BLTPs)... www.pnas.org/doi/10.1073/...

Happy to share the latest from the lab, led by Daniel Alvarez, in collaboration with @lizconibear.bsky.social‬. In this AA-MD tour-de-force, we delve deep into the mechanism and energetics of lipid uptake by bridge-like lipid transfer proteins, and we learn a few interesting things along the way...

When I wrote my latest for @natchem.nature.com on the appropriation of the quantum mechanical lexicon by scam artists, could I have imagined that the surgeon general of Florida would be peddling the woo? Alas, probably. rdcu.be/eXQL (1/3)
