Base editors for simultaneous introduction of C-to-T and A-to-G mutations

We describe base editors that combine both cytosine and adenine base-editing functions. A codon-optimized fusion of the cytosine deaminase PmCDA1, the adenosine deaminase TadA and a Cas9 nickase (Target-ACEmax) showed a high median simultaneous C-to-T and A-to-G editing activity at 47 genomic target...
