Anthropic's Claude Discovers Novel Enzyme System with CRISPR-like Features
Anthropic has announced that its AI model, Claude, autonomously identified a previously uncharacterized enzyme system with features similar to CRISPR. This discovery is one of the first results from the company's newly established life sciences research lab.
The system, known as array associated reverse transcriptases (ART), is primarily found in bacteriophages and consists of a reverse transcriptase, a partner gene, and a long array of evenly spaced DNA repeats. Anthropic noted that the repeat structure resembles the arrays that make CRISPR systems programmable.
To conduct the discovery, Claude was tasked with searching a large DNA sequence database for unusual reverse transcriptases. Approximately 950 agents operated for 21 hours, utilizing around 210 million tokens, ultimately identifying a repeating DNA pattern. This effort yielded over 200,000 reverse transcriptases, from which 3,500 candidate systems were selected for further analysis, narrowing down to 20 for in-depth study.
While the underlying reverse transcriptase had been noted in previous research, Claude was the first to recognize the unique combination of non-coding DNA repeats and an accessory protein that defines the ART system. Initial tests in Anthropic's Bay Area laboratory revealed that the ART repeat array is expressed as distinct short RNAs, although the biological function of the system remains undetermined.
Anthropic has released this work as a preprint and is continuing to conduct further experiments. The company cautioned that despite the similarities with other programmable biological systems, the exact function of ART is still unknown. This project stems from a life sciences research group that Anthropic formed in spring 2026, aimed at exploring how general AI systems can enhance biological discovery through collaboration with scientists in both computational analysis and laboratory research.
