Specific ribosomal proteins are lacking in the Ribo-T precursor. a The results of the quantitative proteomics analysis of the presence of individual r-proteins in mature Ribo-T (the heavy shoulder material) and assembly intermediates (the light shoulder material) from the Ribo-T peak. Red asterisks indicate those r-proteins that are reproducibly underrepresented in the Ribo-T assembly intermediates (less than 60% of the wt 70S ribosome control). Source data are provided in the Source Data file. Error bars represent deviation from the mean (n = 2). b Location of the underrepresented proteins (red) in the small and large ribosomal subunits
