FIGURE 2.
Overview of the tRNA binding sites on the large subunit. CCA oligomers are shown bound at the A site (red) and P site (blue), and the minihelix is shown bound at the E site (orange). 23S rRNA is colored gray and ribosomal proteins are green. Proteins are shown in ribbon format, and RNA all atom, with backbones in darker and bases in lighter colors. The independently solved complex of the L1 arm and L1 protein (Nikulin et al. 2003) was docked into experimental electron density maps of the H. marismortui 50S subunit calculated at 9 Å resolution (Ban et al. 1998).
