Anthropic says Claude helped map the first 3D structure of a vault particle from bacterial life
The cryo-EM structure shows a bacteriophage protein forming a 96-copy shell; the vault's biological function is still unknown and the preprint has been submitted to bioRxiv but is not yet live.
Why it matters
Vault particles are giant hollow protein shells found in most of our cells, discovered in 1986, whose purpose is still a mystery. Anthropic's biology team says Claude helped it show that related proteins in bacteria and phages also assemble into vaults, giving researchers a far simpler system to study. Claude cut a purification that normally takes three days to about 90 minutes and had a first structural model 34 hours later. The function is still unknown, and the peer-review-free preprint is not yet public; watch for the bioRxiv posting and released structures.
Key facts
- Vault built from 96 copies of a phage protein called L05
- Combined mass about 9.5 megadaltons
- Purification cut from about three days to about 90 minutes
- First structural model ready in 34 hours
- Cryo-EM confirmed vault shape for four of seven candidates
- Biological function of vaults still unknown
