Anthropic uses Claude to crack a 40-year biology mystery: first 3D structure of bacterial vault particle

Anthropic's biology research lab used Claude to produce the first 3D structure of a vault particle found in prokaryotic cells, with a preprint submitted to bioRxiv.
- Background: vaults are large hollow protein barrels discovered in 1986, roughly 3x the mass of a ribosome, found in nearly every human cell — but their function has remained unknown for 40 years.
- Claude's role: searching a database of 15 billion predicted proteins, optimizing particle isolation methods, and helping map the vault's structure.
- The team built a vault-like structure in bacteria, mapped it in 3D, and figured out how to make it bigger.
- Significance: even in well-studied E. coli, over a third of 4,400 genes remain poorly understood; vaults are one such enigma, and this is a landmark AI-for-science result in basic biology.
