Anthropic maps the first 3D structure of a prokaryotic vault particle

Source: AnthropicAlso reported by Unite.AI

Anthropic’s biology research lab reported the first 3D structure of a vault particle found in prokaryotic cells: a bacteriophage vault built from 96 copies of one protein, called L05, against 78 in human vaults. Claude helped search sequence literature, optimise the isolation method and map the structure, cutting a vault purification from three days to about 90 minutes. The preprint is submitted to bioRxiv, and the structures and further data are to be released soon.

Why it matters

Researchers get a bacterial vault system that grows quickly, and the phage vault could be adapted as nanocapsules for delivering enzymes.
