Claude discovers a novel enzyme system
Summary
Anthropic launched a new life sciences research group to use AI agents for fundamental biology discovery. In one of their first programs, Claude agents autonomously analyzed over 200,000 reverse transcriptase sequences from a DNA database. After 21 hours and 210 million tokens, one agent spotted a repeating DNA pattern next to a reverse transcriptase gene, which it identified as a CRISPR-like system. The system, called ART (array-associated reverse transcriptases), consists of the RT, an accessory protein, and an array of non-coding DNA repeats that are expressed as distinct small RNAs. Its function remains unknown, but the pattern of repeats is only found together in other programmable DNA-cutting systems, suggesting ART may be a new tool for biotechnology.
Context
Many groundbreaking biological discoveries, such as restriction enzymes, Taq polymerase, and CRISPR, began with scientists noticing unusual patterns in nature. Anthropic formed a life sciences research group in spring 2026 to see if AI models can accelerate such discoveries by collaborating with humans at every step. The team built a lab and developed workflows where Claude agents search massive DNA sequence databases, identify uncharacterized protein families, generate hypotheses, and produce reports for human evaluation. This work aims to create a new paradigm for biology research, with AI handling the genome mining and hypothesis generation while humans perform lab experiments and final judgment.
Approach / What changed
Claude agents were given a prompt to search for interesting examples of reverse transcriptases (RTs) in a massive DNA sequence database. Over 21 hours, roughly 950 agents used 210 million tokens to gather over 200,000 RTs, pick out 3,500 new candidate systems, and narrow to the 20 most compelling candidates. The agents produced human-readable reports with proposed functions and supporting evidence. One agent noticed a repeating DNA pattern next to an RT, counted repeats, measured spacing, compared to known systems, and searched literature. It filed a report for human review, leading to lab characterization of what is now called ART (array-associated reverse transcriptases).
Takeaways
Claude autonomously discovered ART by analyzing raw DNA sequences after scanning over 200,000 reverse transcriptases and narrowing to 20 candidates.
ART consists of a reverse transcriptase, an accessory protein, and an array of non-coding DNA repeats that are expressed as distinct small RNAs, similar to CRISPR arrays.
The discovery demonstrates AI agents can collaborate with humans in hypothesis generation and genome mining, potentially accelerating biological discovery from weeks to hours.
FAQ
What is ART?
ART stands for array-associated reverse transcriptases, a novel enzyme system discovered by Claude. It consists of a reverse transcriptase, an accessory protein, and an array of repeats that are expressed as small RNAs, reminiscent of CRISPR systems. Its exact function is unknown.
How did Claude find ART?
Claude agents searched a database of DNA sequences for interesting reverse transcriptases. After 21 hours and 210 million tokens, one agent noticed a repeating pattern next to an RT and analyzed it further. It produced a report that was reviewed by human scientists, who then tested it in the lab.
Is ART functional?
The article does not confirm its function; experiments are ongoing. However, the repeat structure and expression of small RNAs suggest it may be a programmable system like CRISPR.
