Here, we combine X-ray crystallography and cryo-electron microscopy (cryo-EM) to obtain a molecular model for basal Pol I initiation. The three-subunit CF binds upstream promoter DNA, docks to the Pol I-Rrn3 complex, and loads DNA into the expanded active center cleft of the polymerase. DNA unwinding between the Pol I protrusion and clamp domains enables cleft contraction, resulting in an active Pol I conformation and RNA synthesis. Comparison with the Pol II system suggests that promoter specificity relies on a distinct “bendability” and “meltability” of the promoter sequence that enables contacts between initiation factors, DNA, and polymerase."}],"date_updated":"2021-01-12T08:05:36Z","publist_id":"7204","volume":169,"extern":"1","type":"journal_article","publication_identifier":{"issn":["00928674"]},"intvolume":" 169","language":[{"iso":"eng"}],"publisher":"Cell Press","year":"2017","status":"public","page":"120 - 131.e22","day":"23","date_published":"2017-03-23T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","citation":{"apa":"Engel, C., Gubbey, T., Neyer, S., Sainsbury, S., Oberthuer, C., Baejen, C., … Cramer, P.
