Ribosome biogenesis processes and sets of RBFs in bacteria. a)Schematic view of multi-step ribosome biogenesis including the list of RBFs and tertiary structure of RPs, 70S, 50S and 30S subunits (PDB code: 4YBB, 5UYN, 6ENF, and 1RQU). The structure was visualized using CueMol. b) Boxplot representation of the number of BFs across different phyla in bacteria. Firmicutes are divided into seven groups in the AnnoTree database. * indicates fau-1, recently designated as a gene of RNase W (Vayssières et al. 2024). ** indicates a P-value of ≤ 0.01. -- Molecular Biology and Evolution
