Figure 3.
Correlation of function and location of the small subunit (SSU) and large subunit (LSU) r-proteins of Saccharomyces cerevisiae. Early-acting (yellow), middle-acting (blue), and late-acting (red) r-proteins are mapped onto the crystal structure. (a,c) The subunit interface of the SSU and LSU, respectively. (b,d) The solvent-exposed surface of the SSU and LSU, respectively. Ribosomal RNA (rRNA) and r-proteins are shown in cartoon and surface representation, respectively. Abbreviations: CP, central protuberance; GAC, GTPase-activation center. The crystal structure is adapted from Protein Data bank codes 3U5D and 3U5E.
