Figure 3
(a) Ribosomal protein L9 (dark blue) from one ribosome extends to engage its C-terminal domain in a crystal contact with 16S rRNA of another ribosome, as exemplified by the structure of T. thermophilus 70S in complex with mRNA and tRNA (Selmer et al., 2006BB23). 30S proteins and rRNA are shown in yellow. 50S proteins and rRNA are shown in blue. (b) Comparison of the L9 crystal contact with 16S rRNA in different 70S crystal forms. The structures were superimposed based on the shoulder of 16S rRNA. L9 is shown in different colours in the different structures.
