Appendix 1—table 3. Estimated numbers of ribosomes per cell.

Direct estimates taken from microscopic examinations; proteomic estimates are from averaging of cell-specific estimates for each ribosomal protein subunit. V: cell volume (in μm3); NR,direct: directly estimated copies per cell; NR,raw: estimated copies per cell based on proteomics studies. See Figure 2—source data 1 for further details.
