Anthropic uses Claude to map first 3D structure of a prokaryotic vault particle

The San Francisco AI company’s biology lab reports a phage-derived vault shell of 96 protein copies and faster purification with Claude’s help.

Anthropic said Wednesday that its biology lab, working with Claude, mapped the first three-dimensional structure of a vault particle built from a protein found in bacteriophages, viruses that infect bacteria.

Vaults are large, hollow protein barrels first seen in human cells in 1986.  Scientists still do not know what they do.  Anthropic reported that a phage protein called L05 forms a 96-subunit shell about 54 by 45 nanometers, with roughly 25% more enclosed volume than human vaults.

Under researchers’ direction, Claude searched protein databases, designed DNA constructs, helped speed purification from about three days to about 90 minutes, and processed cryo-electron microscope data.  A first structural model was ready in 34 hours, the company said.

Vault function remains unknown.  Anthropic has not yet shown that these vaults form in the bacteria or phages where the genes occur naturally.  A preprint is headed to bioRxiv.
