Distribution of RNA and protein on the chloro-ribosome with positions of PSRPs and PRP extensions highlighted. (A and B) 30S subunit: pale yellow, rRNA; yellow, PRPs; green, PRP extensions; and red, PSRPs. (C and D) 50S subunit: blue, rRNA; purple, PRPs, green, PRP extensions; and red, PSRP5. In A/C and B/D, subunits are shown from the interface and solvent sides, respectively. To avoid visual complexity, only densities corresponding to PRP extensions (with suffix “ext”), conformational changes (with suffix “c”), or shifts in the position of PRPs (with suffix “s”) with respect to their bacterial orthologs, and PSRPs (1–5), are labeled. Numbers following S or L identify small and large subunit PRPs, respectively, and numbers following h or H identify 16S and 23S rRNA helices within small and large subunits, respectively. Landmarks: b, body of the 30S subunit; pRRF, domain I of pRRF; St, L7/L12 stalk of the 50S subunit. All other landmarks are the same as in Fig. 1.
