Ribosomal protein composition of control and ΔSRL particles isolated from cells or reconstituted in vitro. Shown are normalized isotope ratios, indicating the relative abundance of each 50S protein with respect to the spike-in standard. Bars represent the mean ± SEM of three independent experiments, and individual data points (circles) are superimposed. Green, isolated control; gold, isolated ΔSRL; blue, reconstituted control; orange, reconstituted ΔSRL.
