Model of the aa-tRNA accommodation pathway (from [28]; copyright 2005 National Academy of Sciences USA). Stage 1 represents the hypothetic state after the dissociation of EF-Tu, but before the onset of tRNA accommodation. Stage 2 shows the movement of the aminoacyl-tRNA body (except for the 3′CCA portion of tRNA) towards the PTC. In stage 3, the aminoacyl-tRNA body is accommodated. During stage 4, the aminoacyl-tRNA 3′-CCA end is accommodated into the PTC. The schematics depict the process of accommodation.
