- Ribosome recycling factor (RRF) together with elongation factor G (EF-G) disassembles the post- termination ribosomal complex. Inhibitors of translocation, thiostrepton, viomycin and aminoglycosides, inhibited the release of tRNA and mRNA from the post-termination complex. In contrast, fusidic acid and a GTP analog that fix EF-G to the ribosome, allowing one round of tRNA translocation, inhibited mRNA but not tRNA release from the complex. The release of tRNA is a prerequisite for mRNA release but partially takes place with EF-G alone. The data are consistent with the notion that RRF binds to the A-site and is translocated to the P-site, releasing deacylated tRNA from the P- and E-sites. The final step, the release of mRNA, is accompanied by the release of RRF and EF-G from the ribosome. With the model post-termination complex, 70S ribosomes were released from the post-termination complex by the RRF reaction and were then dissociated into subunits by IF3.
