Claude helps solve 40-year vault protein mystery: Anthropic builds it in bacteria, maps 3D

Anthropic researchers used Claude to tackle a 40-year-old biology mystery: vaults, hollow protein barrels found in nearly every human cell whose function remains unknown.
Key advances:
- Claude searched a database of 15 billion predicted proteins; the team found a gene from a bacteriophage and inserted it into E. coli, which self-assembled a sealed barrel of 96 identical subunits.
- Duplicating two protein segments still assembled the barrel, with 20% more internal volume.
- Purification dropped from 3 days to 90 minutes; Claude produced the first 3D model from cryo-EM data in 34 hours versus weeks normally.
- New clue: each subunit has a pocket holding a small molecule resembling coenzyme A.
The vault's true purpose remains open, but scientists now have a testable lead and a barrel they can grow and redesign in the lab.
