The MerR-family proteins represent a unique family of bacteria transcription factors (TFs), which activate transcription in a manner distinct from canonical ones. Here, we report a cryo-EM structure of a B. subtilis transcription activation complex comprising B. subtilis six-subunit (2αββ'ωε) RNA Polymerase (RNAP) core enzyme, σ, a promoter DNA, and the ligand-bound B. subtilis BmrR, a prototype of MerR-family TFs. The structure reveals that RNAP and BmrR recognize the upstream promoter DNA from opposite faces and induce four significant kinks from the -35 element to the -10 element of the promoter DNA in a cooperative manner, which restores otherwise inactive promoter activity by shortening the length of promoter non-optimal -35/-10 spacer. Our structure supports a DNA-distortion and RNAP-non-contact paradigm of transcriptional activation by MerR TFs. 履歴 登録 2020年7月18日 - ヘッダ(付随情報) 公開 2020年12月16日 - マップ公開 2020年12月16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
