Citation | Journal: Science / Year: 2018Title: Structure of the nuclear exosome captured on a maturing preribosome. Authors: Jan Michael Schuller / Sebastian Falk / Lisa Fromm / Ed Hurt / Elena Conti / ![]() Abstract: The RNA exosome complex processes and degrades a wide range of transcripts, including ribosomal RNAs (rRNAs). We used cryo-electron microscopy to visualize the yeast nuclear exosome holocomplex ...The RNA exosome complex processes and degrades a wide range of transcripts, including ribosomal RNAs (rRNAs). We used cryo-electron microscopy to visualize the yeast nuclear exosome holocomplex captured on a precursor large ribosomal subunit (pre-60) during 7-to-5.8 rRNA processing. The cofactors of the nuclear exosome are sandwiched between the ribonuclease core complex (Exo-10) and the remodeled "foot" structure of the pre-60 particle, which harbors the 5.8 rRNA precursor. The exosome-associated helicase Mtr4 recognizes the preribosomal substrate by docking to specific sites on the 25 rRNA, captures the 3' extension of the 5.8 rRNA, and channels it toward Exo-10. The structure elucidates how the exosome forms a structural and functional unit together with its massive pre-60 substrate to process rRNA during ribosome maturation. | |||||||||
