# Anthropic says Claude helped solve the first 3D structure of a vault particle from a bacterium

Claude searched about 15 billion predicted proteins, seven of 15 lab-tested candidates formed vault-like particles, and cryo-electron microscopy confirmed four, according to a preprint that has not been peer reviewed.

Anthropic's biology team reported on November 4 that Claude helped find and structurally solve a vault particle outside the animal kingdom. Vaults are large, hollow protein shells, and their biological function is still unknown. The work is…
