Figure 7. The mammalian elongation circle features unique motions of the 40S subunit.

Figure 7

Cartoon representation of the eukaryotic elongation circle highlighting the individual subunit motions necessary to convert one functional intermediate state to the next. Movements of the small ribosomal subunit shared with the prokaryotic system are noted in black, while eukaryotic specific intersubunit movements, i.e. rolling and back-rolling, are noted in red.
