In eukaryotes, final assembly of the PTC occurs in the cytoplasm by insertion of the ribosomal protein Rpl10 (uL16). We determine structures of six intermediates in late nuclear and cytoplasmic maturation of the large subunit that reveal a tightly-choreographed sequence of protein and RNA rearrangements controlling the insertion of Rpl10. We also determine the structure of the biogenesis factor Yvh1 and show how it promotes assembly of the P stalk, a critical element for recruitment of GTPases that drive translation. Together, our structures provide a blueprint for final assembly of a functional ribosome. Tightly-orchestrated rearrangements govern catalytic center assembly of the ribosome.,Zhou Y, Musalgaonkar S, Johnson AW, Taylor DW Nat Commun. 2019 Feb 27;10(1):958. doi: 10.1038/s41467-019-08880-0.
