Claude unlocks new enzyme system with crispr-like features

Anthropic's life sciences team has unveiled a novel enzyme system, ART, discovered by Claude with minimal human guidance. The system, found in bacteriophages, features DNA repeats similar to CRISPR, suggesting potential programmable functions. Feng Zhang, a CRISPR pioneer, praised the discovery, noting Claude's ability to autonomously identify patterns in vast DNA datasets. The system includes a reverse transcriptase, an associated DNA array, and an unknown protein, all previously uncharacterized. Over 200,000 RTs were analyzed, narrowing down to 20 candidates, with ART being the most compelling. Lab tests confirmed the presence of distinct RNAs linked to the array, hinting at a mechanism akin to CRISPR. The team emphasizes AI's role in accelerating biological discovery, sharing findings through a pre-print and inviting collaboration. The Life Sciences Verification Program now offers enhanced AI models for biology research, reflecting Anthropic's commitment to advancing scientific exploration. Claude's discovery process mirrors human scientific methods, involving hypothesis generation, literature review, and experimental validation. The system's potential applications in gene editing and biotechnology are under investigation. Anthropic's lab, operating at BSL-1 and BSL-2 levels, focuses on non-human pathogen work, leveraging AI to streamline complex molecular biology workflows. The team's prior work includes CRISPR evolution studies and enzyme discovery for gene therapies, underscoring their expertise in computational biology. By integrating AI into hypothesis testing, Anthropic aims to transform how biological systems are identified and studied, offering a scalable approach to scientific innovation.
