# Claude Helps Anthropic Researchers Solve the First 3D Structure of a Bacterial Vault Particle

The model searched about 15 billion predicted proteins and designed DNA for candidates. Seven of 15 expressed proteins formed vault-like shells, and Anthropic documents two model errors, one of which cost about two weeks.

Anthropic's biology team reported on November 4 the first three-dimensional structure of a vault particle from a prokaryote. The particle is formed by L05, a bacteriophage protein. Vaults are large hollow protein shells first identified in…
