In this study, we analyze physiologic prokaryotic ribosome biogenesis by isolating bona fide pre-50S subunits from an Escherichia coli strain with the biogenesis factor ObgE, affinity tagged at its native gene locus. Our integrative structural approach reveals a network of interacting biogenesis factors consisting of YjgA, RluD, RsfS, and ObgE on the immature pre-50S subunit. In addition, our study provides mechanistic insight into how the GTPase ObgE, in concert with other biogenesis factors, facilitates the maturation of the 50S functional core and reveals both conserved and divergent evolutionary features of ribosome biogenesis between prokaryotes and eukaryotes. Snapshots of native pre-50S ribosomes reveal a biogenesis factor network and evolutionary specialization.,Nikolay R, Hilal T, Schmidt S, Qin B, Schwefel D, Vieira-Vieira CH, Mielke T, Burger J, Loerke J, Amikura K, Flugel T, Ueda T, Selbach M, Deuerling E, Spahn CMT Mol Cell. 2021 Mar 18;81(6):1200-1215.e9. doi: 10.1016/j.molcel.2021.02.006.
