引用ジャーナル : Nat Chem Biol / 年 : 2021タイトル : CueR activates transcription through a DNA distortion mechanism.著者 : Chengli Fang / Steven J Philips / Xiaoxian Wu / Kui Chen / Jing Shi / Liqiang Shen / Juncao Xu / Yu Feng / Thomas V O'Halloran / Yu Zhang / 要旨 : The MerR-family transcription factors (TFs) are a large group of bacterial proteins responding to cellular metal ions and multiple antibiotics by binding within central RNA polymerase-binding regions ... The MerR-family transcription factors (TFs) are a large group of bacterial proteins responding to cellular metal ions and multiple antibiotics by binding within central RNA polymerase-binding regions of a promoter. While most TFs alter transcription through protein-protein interactions, MerR TFs are capable of reshaping promoter DNA. To address the question of which mechanism prevails, we determined two cryo-EM structures of transcription activation complexes (TAC) comprising Escherichia coli CueR (a prototype MerR TF), RNAP holoenzyme and promoter DNA. The structures reveal that this TF promotes productive promoter-polymerase association without canonical protein-protein contacts seen between other activator proteins and RNAP. Instead, CueR realigns the key promoter elements in the transcription activation complex by clamp-like protein-DNA interactions: these induce four distinct kinks that ultimately position the -10 element for formation of the transcription bubble. These structural and biochemical results provide strong support for the DNA distortion paradigm of allosteric transcriptional control by MerR TFs. 履歴 登録 2019年11月21日 - ヘッダ(付随情報) 公開 2020年9月30日 - マップ公開 2020年9月30日 - 更新 2024年3月27日 - 現状 2024年3月27日 処理サイト : PDBj / 状態 : 公開
