Gene transcription is carried out by RNA polymerase (RNAP) and requires the conversion of the initial closed promoter complex, where DNA is double stranded, to a transcription-competent open promoter complex, where DNA is opened up. In bacteria, RNAP relies on σ factors for its promoter specificities. Using a special form of sigma factor (σ), which forms a stable closed complex and requires its activator that belongs to the AAA+ ATPases (ATPases associated with diverse cellular activities), we obtained cryo-electron microscopy structures of transcription initiation complexes that reveal a previously unidentified process of DNA melting opening. The σ amino terminus threads through the locally opened up DNA and then becomes enclosed by the AAA+ hexameric ring in the activator-bound intermediate complex. Our structures suggest how ATP hydrolysis by the AAA+ activator could remove the σ inhibition while helping to open up DNA, using σ amino-terminal peptide as a pry bar. 履歴 登録 2022年1月20日 - ヘッダ(付随情報) 公開 2022年11月9日 - マップ公開 2022年11月9日 - 更新 2024年7月17日 - 現状 2024年7月17日 処理サイト : PDBe / 状態 : 公開
