Applications of toxin-antitoxin systems in synthetic biology by Jianzhong Lin, Yunxue Guo, Jianyun Yao, Kaihao Tang, Xiaoxue Wang

“…Toxin-antitoxin (TA) systems are ubiquitous in bacteria and archaea. Most are composed of two neighboring genetic elements, a stable toxin capable of inhibiting crucial cellular processes, including replication, transcription, translation, cell division and membrane integrity, and an unstable antitoxin to counteract the toxicity of the toxin. …”

Structural and DNA end resection study of the bacterial NurA-HerA complex by Jieyu Yang, Yiyang Sun, Ying Wang, Wanshan Hao, Kaiying Cheng

“…Abstract Background The nuclease NurA and the ATPase/translocase HerA play a vital role in repair of double-strand breaks (DSB) during the homologous recombination in archaea. A NurA-HerA complex is known to mediate DSB DNA end resection, leading to formation of a free 3′ end used to search for the homologous sequence. …”
