Anthropic reports Claude-assisted discovery of an uncharacterized enzyme system
Anthropic announced a biology research group and early results on September 23: Claude identified an unusual enzyme system called array-associated reverse transcriptases, or ART. Human scientists performed subsequent laboratory work. Its repeating genetic sequences resemble features of CRISPR, but its biological function remains unknown.

Reverse transcriptases copy RNA into DNA. The underlying enzyme had appeared in earlier studies; the reported discovery concerns associated repeat sequences and an additional protein, rather than discovery of that enzyme itself.
Anthropic says roughly 950 agents searched for 21 hours using 210 million tokens. The workflow generated and narrowed candidates before human review and experiments, illustrating substantial computational effort behind the reported result.
What remains unclear
ART’s function and practical applications remain undetermined.
