We show that the three TFIIE winged-helix (WH) domains form a heterodimer, with the Tfa1 (TFIIEα) WH binding the Pol II clamp and the Tfa2 (TFIIEβ) tandem WH domain encircling promoter DNA that becomes single-stranded in the open complex. Ssl2 lies adjacent to TFIIE, enclosing downstream promoter DNA. Unlike previous proposals, comparison of the PIC and open-complex models strongly suggests that Ssl2 promotes DNA opening by functioning as a double-stranded-DNA translocase, feeding 15 base pairs into the Pol II cleft. Right-handed threading of DNA through the Ssl2 binding groove, combined with the fixed position of upstream promoter DNA, leads to DNA unwinding and the open state. #5: ![]() タイトル: A Molecular Toolkit to Visualize Native Protein Assemblies in the Context of the Human Disease 著者: Gilmore BL / Winton CE / Demmert AC / Tanner JR / Bowman S / Karageorge V / Patel K / Sheng Z / Kelly DF | |||||||||
