The team produced vault-like particles in *E. coli* from 44 candidate proteins, with seven forming vaults under electron microscopy. Claude assisted in designing DNA constructs, optimizing purification, and running cryo-electron microscopy workflows, cutting processing time from weeks to days in some cases.\n\nThe research identified a vault particle (**L05**) composed of **96 protein copies**, distinct from mammalian vaults. By duplicating wall segments, the team enlarged the shell’s volume by **20%**, demonstrating tunability. Claude also flagged errors—like a DNA-design mistake delaying work by **two weeks**—and improved subsequent iterations. The study, submitted to **bioRxiv**, highlights AI’s role in accelerating structural biology but notes unresolved questions, such as the vaults’ biological function or the identity of a bound ligand.","keyPoints":["Claude mapped a bacteriophage vault protein at **3.2 Å resolution** in *E. coli*, a first for prokaryotic vaults","Researchers resized vault shells by duplicating protein repeats, increasing volume by **20%** without disrupting assembly","Claude’s workflow reduced cryo-EM processing time from weeks to **34 hours** but introduced errors requiring human correction"],"whyItMatters":"This work shows how AI can accelerate structural biology, enabling faster protein engineering for nanocapsules or drug delivery. The tunable vaults could inspire synthetic biology tools, though their natural function remains unclear.","category":{"slug":"research","name":"Research","url":"https://digestai.news/category/research"},"entities":{"companies":["Anthropic"],"models":["Claude","Claude Science","Claude Code"],"people":[]},"firstPublishedAt":"2026-11-04T20:12:05Z","updatedAt":"2026-11-04T20:12:05Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"Unite.AI","title":"Anthropic Uses Claude to Show Bacterial and Phage Proteins Form Vaults","url":"https://unite.ai/anthropic-uses-claude-to-show-bacterial-and-phage-proteins-form-vaults","publishedAt":"2026-11-04T20:12:05Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Anthropic uses Claude to map bacteriophage vault protein at 3.2 Å resolution\", 4 November 2026, https://digestai.news/story/anthropic-uses-claude-to-map-bacteriophage-vault-protein-at-3-2-a-reso","publisher":"Digest AI","title":"Anthropic uses Claude to map bacteriophage vault protein at 3.2 Å resolution","datePublished":"2026-11-04T20:12:05Z","url":"https://digestai.news/story/anthropic-uses-claude-to-map-bacteriophage-vault-protein-at-3-2-a-reso"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
