The tmRNA system for translational surveillance and ribosome rescue
SD Moore, RT Sauer - Annu. Rev. Biochem., 2007 - annualreviews.org
The tmRNA system performs translational surveillance and ribosome rescue in all
eubacteria and some eukaryotic organelles. This system intervenes when ribosomes read to …

Biology of trans-Translation
The trans-translation mechanism is a key component of multiple quality control pathways in
bacteria that ensure proteins are synthesized with high fidelity in spite of challenges such as …

The weird and wonderful world of bacterial ribosome regulation
In every organism, translation of the genetic information into functional proteins is performed
on the ribosome. In Escherichia coli up to 40% of the cell's total energy turnover is …

The tmRNA ribosome-rescue system
The bacterial tmRNA quality control system monitors protein synthesis and recycles stalled
translation complexes in a process termed “ribosome rescue.” During rescue, tmRNA acts …

Structures of tmRNA and SmpB as they transit through the ribosome
In bacteria, trans-translation is the main rescue system, freeing ribosomes stalled on
defective messenger RNAs. This mechanism is driven by small protein B (SmpB) and …

Visualizing tmRNA entry into a stalled ribosome
Bacterial ribosomes stalled on defective messenger RNAs (mRNAs) are rescued by tmRNA,
an∼ 300-nucleotide-long molecule that functions as both transfer RNA (tRNA) and mRNA …

tmRNA-mediated trans-translation as the major ribosome rescue system in a bacterial cell
Transfer messenger RNA (tmRNA; also known as 10Sa RNA or SsrA RNA) is a small RNA
molecule that is conserved among bacteria. It has structural and functional similarities to …

Structural basis for functional mimicry of long-variable-arm tRNA by transfer-messenger RNA
tmRNA and small protein B (SmpB) are essential trans-translation system components. In
the present study, we determined the crystal structure of SmpB in complex with the entire …

An overview of the bacterial SsrA system modulating intracellular protein levels and activities
In bacteria, the truncated forms of mRNAs, which usually lack a stop codon, are occasionally
generated by premature termination of gene transcription and/or endo-or exonucleolytic …

Trans-Translation: The tmRNA-Mediated Surveillance Mechanism for Ribosome Rescue, Directed Protein Degradation, and Nonstop mRNA Decay
The accurate flow of genetic information from DNA to RNA to protein is essential for all living
organisms. An astonishing array of quality-assurance mechanisms have evolved to ensure …
