Citation | Journal: Science / Year: 2020Title: 90 pre-ribosome transformation into the primordial 40 subunit. Authors: Jingdong Cheng / Benjamin Lau / Giuseppe La Venuta / Michael Ameismeier / Otto Berninghausen / Ed Hurt / Roland Beckmann / ![]() Abstract: Production of small ribosomal subunits initially requires the formation of a 90 precursor followed by an enigmatic process of restructuring into the primordial pre-40 subunit. We elucidate this ...Production of small ribosomal subunits initially requires the formation of a 90 precursor followed by an enigmatic process of restructuring into the primordial pre-40 subunit. We elucidate this process by biochemical and cryo-electron microscopy analysis of intermediates along this pathway in yeast. First, the remodeling RNA helicase Dhr1 engages the 90 pre-ribosome, followed by Utp24 endonuclease-driven RNA cleavage at site A, thereby separating the 5'-external transcribed spacer (ETS) from 18 ribosomal RNA. Next, the 5'-ETS and 90 assembly factors become dislodged, but this occurs sequentially, not en bloc. Eventually, the primordial pre-40 emerges, still retaining some 90 factors including Dhr1, now ready to unwind the final small nucleolar U3-18 RNA hybrid. Our data shed light on the elusive 90 to pre-40 transition and clarify the principles of assembly and remodeling of large ribonucleoproteins. | |||||||||
