Claude gene discovery (novel enzyme system)

This is an Anthropic research announcement introducing its new life sciences research lab and early results from a program using Claude agents to search DNA sequence databases for uncharacterized protein families. Claude agents identified a previously uncharacterized enzyme system in bacteriophages, which Anthropic calls array-associated reverse transcriptases (ART). The system pairs a reverse transcriptase with an array of non-coding DNA repeats and an accessory protein of unknown function.

According to Anthropic, about 950 Claude agents used roughly 210 million tokens over 21 hours to survey reverse transcriptase families. The underlying RT, from a jumbo phage, had been described before, but Claude appears to be the first to notice the associated repeat array and accessory protein. Anthropic's scientists supplied the initial prompt and did the wet-lab testing. The characteristics resemble a handful of other programmable systems that cut, copy or paste DNA, but the function of ART is not yet known.

The results are shared as a pre-print and a blog post, not as a product. Feng Zhang (MIT/Broad Institute) called the finding intriguing and worthy of further investigation. Limits: the function is unresolved, the work is early-stage, and some outside commentators have said its significance is overstated. The lab is in the Bay Area, works at BSL-1 and BSL-2 only, and all lab work is done by human scientists.
