Last year, atomic structures of the 50S ribosomal subunit from Haloarcula m
arismortui and of the 30S ribosomal subunit from Thermus thermophilus were
published. A year before that, a 7.8 Angstrom resolution electron density m
ap of the 70S ribosome from T. thermophilus appeared. This information is r
evolutionizing our understanding of protein synthesis.
