Comparison of the location of archaea/eukaryote-specific r-proteins in archaeal and eukaryotic ribosomes. Intersubunit view of individual subunits of Pyrococcus furiosus (A) and Saccharomyces cerevisiae (B) (left – SSU (30S, 40S), right – LSU (50S, 60S) are shown. rRNA and universally conserved r-proteins are highlighted in grey and dark blue, respectively. Archaea/eukaryote-specific proteins are colored red and labelled. Domain-specific proteins are yellow. Approximate positions of the A-, P- and E-sites for tRNA binding are indicated. Protein groups and nomenclature are according to [8]. PDB coordinates 4V6U for P. furiosus [3] and 4V88 for S. cerevisiae [4] were rendered in PyMol.
