引用ジャーナル : Proc Natl Acad Sci U S A / 年 : 2023タイトル : A general mechanism for transcription bubble nucleation in bacteria.著者 : Andreas U Mueller / James Chen / Mengyu Wu / Courtney Chiu / B Tracy Nixon / Elizabeth A Campbell / Seth A Darst / 要旨 : Bacterial transcription initiation requires σ factors for nucleation of the transcription bubble. The canonical housekeeping σ factor, σ, nucleates DNA melting via recognition of conserved bases ... Bacterial transcription initiation requires σ factors for nucleation of the transcription bubble. The canonical housekeeping σ factor, σ, nucleates DNA melting via recognition of conserved bases of the promoter -10 motif, which are unstacked and captured in pockets of σ. By contrast, the mechanism of transcription bubble nucleation and formation during the unrelated σ-mediated transcription initiation is poorly understood. Herein, we combine structural and biochemical approaches to establish that σ, like σ, captures a flipped, unstacked base in a pocket formed between its N-terminal region I (RI) and extra-long helix features. Strikingly, RI inserts into the nascent bubble to stabilize the nucleated bubble prior to engagement of the obligate ATPase activator. Our data suggest a general paradigm of transcription initiation that requires σ factors to nucleate an early melted intermediate prior to productive RNA synthesis. 履歴 登録 2022年11月4日 - ヘッダ(付随情報) 公開 2023年4月5日 - マップ公開 2023年4月5日 - 更新 2024年1月17日 - 現状 2024年1月17日 処理サイト : RCSB / 状態 : 公開
