To maintain genome integrity and ensure cell survival, bacteria have evolved several DNA repair pathways to repair different types of DNA damage and non-canonical bases, including strand breaks, nucleotide modifications, cross-links, mismatches and ribonucleotide incorporations. In this Review, Wozniak and Simmons provide a contemporary discussion of the excision-based mechanisms bacteria use to repair the diverse set of lesions they encounter.
