Anthropic says it obtained the first 3D structure of a prokaryotic vault particle

Anthropic says it obtained the first 3D structure of a vault particle found in prokaryotic cells. The company says Claude helped search sequence literature, optimize particle isolation and map the structure; the work was submitted to bioRxiv, but its preprint was not yet available when the post was published.

Vault particles are large, hollow protein structures whose function remains unknown. Anthropic’s team says it found that more vault proteins—including those in prokaryotes and bacteriophages—can assemble into complete or vault-like particles. Anthropic says it has not yet determined their biological function and describes the result as a possible way to study them in simpler bacterial systems.
