Citation | Journal: Nat Commun / Year: 2016 Title: RNA polymerase I-Rrn3 complex at 4.8 Å resolution. Authors: Christoph Engel / Jürgen Plitzko / Patrick Cramer / Abstract: Transcription of ribosomal DNA by RNA polymerase I (Pol I) requires the initiation factor Rrn3. Here we report the cryo-EM structure of the Pol I-Rrn3 complex at 4.8 Å resolution. The structure ...Transcription of ribosomal DNA by RNA polymerase I (Pol I) requires the initiation factor Rrn3. Here we report the cryo-EM structure of the Pol I-Rrn3 complex at 4.8 Å resolution. The structure reveals how Rrn3 binding converts an inactive Pol I dimer into an initiation-competent monomeric complex and provides insights into the mechanisms of Pol I-specific initiation and regulation. | |||||||||
