SRP408306 PRJNA895108 Acinetobacter baumannii DNA damage response is impaired by knockout DdaA gene We found a novel protein(WP_000117148.1, termed DdaA) is the prime regulator of DNA damage response of Moraxellaceae. Using Acinetobacter baumannii as model organism, we found knock out DdaA seriously impaired DNA damage response of Acinetobacter baumannii. Acinetobacter baumannii ATCC 17978
