Anthropic's Claude AI discovers novel enzyme system resembling CRISPR

Anthropic announced on September 23, 2026, that its Claude AI model helped discover a novel enzyme system, named array-associated reverse transcriptases (ART), which resembles CRISPR gene-editing technology. The discovery marks the first output from Anthropic's new life sciences group and its recently established wet lab in the San Francisco Bay Area. However, some scientific experts have urged caution, suggesting Anthropic may have oversold the significance of the AI-driven finding.

Anthropic wet lab expansion

• ▪Anthropic's life sciences group aims to use Claude artificial intelligence agents to analyze massive DNA datasets and identify proteins for scientists to test in physical laboratories
• ▪Anthropic established a physical wet lab in the San Francisco Bay Area to expand its life sciences and drug-related research beyond computer-based work

ART system characteristics

• ▪The array-associated reverse transcriptases system discovered by Claude contains repeating DNA sequences resembling CRISPR, an array of non-coding DNA sequences, and an additional protein of unknown function
• ▪Anthropic named a novel enzyme system discovered by Claude "array-associated reverse transcriptases," or ART, which is built around a reverse transcriptase enzyme that copies RNA into DNA

Scientific community skepticism

• ▪While the underlying reverse transcriptase enzyme in the array-associated reverse transcriptases system discovered by Claude had been identified in previous studies, Anthropic stated that Claude was the first to recognize the broader system's key features
• ▪Some scientific experts met Anthropic's September 23, 2026 announcement about Claude's enzyme discovery with caution, suggesting that the artificial intelligence company may have oversold the significance of the array-associated reverse transcriptases enzyme system discovery

Debatable claims

• ▪Anthropic oversold the scientific significance of its ART enzyme discovery
• ▪AI companies are better positioned than traditional labs to discover novel biological systems
• ▪The ART system is a viable pathway to new gene-editing technologies
