Architecture of the ribosome subunits (40S subunit on the left site and 60S subunit on the right site) with new protein nomenclature. Ribosome proteins from all three domains (bacteria, archaea and eukaryotes) have the prefix ‘u’ (universal). Bacteria-specific proteins have the prefix ‘b’ (bacterial). Eukaryote-specific proteins have the prefix ‘e’ (eukaryote). (a) Interface view of the 60S and 40S subunits. Landmarks include the head, body (Bd) and platform (Pt) of 40S as well as the central protuberance (CP), L1-stalk and P-stalk of 60S. (b) Solvent-side view of the 60S and 40S subunits.
