Some studies earlier this year found that MSA pairing quality has no impact on structure prediction of co-evolving hetero-oligomeric complexes. I'm curious if co-folding models trained with the MSA pairing approach by @yoakiyama would do better nitter.cf/BioSpace9/status/20442…
Dissecting the Black Box of AlphaFold in Protein-Protein Complex Assembly
biorxiv.org/content/10.64898…
この研究は、AlphaFoldがどのようにタンパク質複合体の構造を予測しているのかを理解することを目指しています。
特に、従来重要と考えられていた共進化情報ではなく、単体タンパク質の形状や界面の形の相補性が重要であるという視点で解析が行われています。
モデル内部の情報伝播を可視化することで、まず単体構造が決まり、その後に相互作用が推定されるという段階的な推論プロセスが示されています。
この理解は、protein designにおいて複合体を設計する際に、どの要素を重視すべきかを考える上で重要な示唆を与えます。

Excited to report the first de novo enzyme catalyzing two of the most energetically demanding reactions in biology—phosphomonoester and phosphodiester hydrolysis—with catalytic efficiencies comparable to natural enzymes! 🚀
desB was designed zero-shot with dEVA. No structure prediction, no pre-defined motif, no reaction-intermediates. 🧵

Today we're dropping the "beta" tag from Adaptyv, launching our new website and announcing our $8M seed round.
When we started Adaptyv a few years ago, our core belief was: AI models for biology are only as good as the experimental data they're trained on and the hypotheses they can test in the real world.
Now, after a year of working with many great partners, we’ve scaled our infrastructure to the point that we're now open to anyone who wants to use our platform!
Overall, this year, over 30 companies started using Adaptyv to validate their protein designs - from some of the biggest pharmas to frontier AI labs to many, many techbio startups. We've run hundreds of experiments, tested well over 10,000 proteins this year and are generating the data that validates the best AI models currently in development.

Chai Discovery just released their new model Chai-2, validated on Adaptyv!
Chai-2 enables generation of de novo proteins and epitope-specific antibodies using a multimodal generative architecture that integrates all-atom structure prediction and generative modeling.
Chai tested many of their new protein designs using our high-throughput wet lab at Adaptyv to get high quality data to improve their AI models in as little as two weeks per round.
Excited to share our new AllMetal3D model building on Metal3D. AllMetal3D predicts the location, identity and geometry of the major biologically relevant metal ions doi.org/10.1101/2025.02.05.6…
We compared to a few other tools that perform either metal identity prediction or location prediction and found that is very important to include negative classes during training and also cluster metal ions by biological similarity.
In earlier work, we already analyzed how AllMetal3D given a structural input and no information about metal stoichiometry fares against co-folding methods given metal stoichiometry but no structure: doi.org/10.1101/2024.05.28.5…

Thank you to everyone who came to MLSB this year!!
We are collecting feedback in a short 2 minute survey (and more data means maybe next year we'll train a new model... or just get a bigger room 😄)

Unbelievable how expensive BioRender is. @MPDL is paying 673 413 USD for a two year license for a software that isn't even compatible with open access publishing (even if BioRender claims otherwise). ted.europa.eu/en/notice/-/de…
Anyone working at MPG willing to share the license conditions ? I'd be curious if they have special terms. For the last contract they didn't. The info should be on this page: soli.mpdl.mpg.de/en/software…
Now available: open source UI with @Gradio for Boltz-1 by @GabriCorso @jeremyWohlwend
Check it out on HuggingFace spaces. h/t @huggingface for community L4 GPU: huggingface.co/spaces/simond…
Thrilled to announce Boltz-1, the first open-source and commercially available model to achieve AlphaFold3-level accuracy on biomolecular structure prediction! An exciting collaboration with @jeremyWohlwend, @pas_saro and an amazing team at MIT and Genesis Therapeutics. A thread!
Both the input component and the molecule output component are individually reusable. Simply pip install gradio_cofoldinginput or gradio_molecule3d.
This is a great effort by NIH. All illustrations financed by public money should similarly be available for others to reuse in the correct format (vector). The key is that NIH BioArt is not only free but also comes with a permissive license! #OpenScience

Gave an intro to Docker + @huggingface Spaces + @Gradio at European Rosettacon 2024 for protein people. Maybe my slides are also interesting to the wider community: duerrsimon.github.io/docker_…
You can play with the demos directly in the slides thanks to @Slidevjs 😎
