Third-generation base editors consist of a catalytically disabled Cas9 fused to a cytidine deaminase and a base excision repair inhibitor, enabling efficient, precise editing of individual base pairs in DNA. Here the authors describe engineering and protein delivery of base editors to improve their DNA specificity and enable specific base editing in live animals.
