Researchers from NUS Medicine have developed an AI-guided approach to improve compact base editors, enhancing precision and safety in gene-editing for potential therapeutic use.

• Technology Advancement: Use of AlphaFold3 to modify the SsdAtox enzyme, improving DNA editing efficiency and reducing unintended DNA damage.
• Performance Results: Optimised variants achieved up to 11.8x higher efficiency, reduced DNA breaks, and lowered cellular toxicity, with a 31-fold improvement based on a performance index.
• Clinical Relevance: Smaller enzyme size improves compatibility with viral delivery systems such as AAVs, supporting potential applications in treating genetic diseases.
