Properties of cytidine and adenosine deaminases lead to off-target effects for cytosine base editors (CBEs) and adenine base editors (ABEs). Here the authors report that 25 TadA orthologs could be engineered to generate functional ABEs, CBEs or ACBEs via single/double mutations with minimised off-targets.
