# Anthropic says Claude helped resolve the first 3D structure of a vault particle from bacterial life

The preprint reports a shell built from 96 copies of a protein called L05, and it also records Claude's errors, including a mirrored density map that human researchers had to catch and a mistake that cost two weeks.

Anthropic's biology team reported on November 4 that it used Claude to reconstruct the 3D structure of a vault particle derived from a virus that infects bacteria. Vaults are large hollow protein shells first described in 1986, and their fu…
