# Claude helped Anthropic's biology lab produce the first 3D structure of a vault particle from a prokaryote

Seven of 15 candidate proteins assembled into vault-like particles, and cryo-electron microscopy confirmed four. Anthropic also lists a Claude-written protocol error that cost about two weeks.

Anthropic's biology research lab published work on November 4 reporting the first 3D structure of a vault particle found in prokaryotic cells. Vaults are large, hollow ribonucleoprotein shells first described in eukaryotes in 1986, and thei…
