Cytosine Base Editing in Bacteria

Base editing is a new genome editing technology that enables DNA base mutations without requiring double-stranded DNA backbone cleavage or a donor template. It has been widely used for genome engineering of eukaryotic and prokaryotic microorganisms. In this chapter, we describe a routine protocol for cytosine base editing in two model bacteria Corynebacterium glutamicum and Bacillus subtilis. The protocol can be adapted to base editing in other bacteria with modifications.
