In vitro trans-translation of Thermus thermophilus: ribosomal protein S1 is not required for the early stage of trans-translation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Transfer-messenger RNA (tmRNA) plays a dual role as a tRNA and an mRNA in trans-translation, during which the ribosome replaces mRNA with tmRNA encoding the tag-peptide. These processes have been suggested to involve several tmRNA-binding proteins, including SmpB and ribosomal protein S1. To investigate the molecular mechanism of trans-translation, we developed in vitro systems using purified ribosome, elongation factors, tmRNA and SmpB from Thermus thermophilus. A stalled ribosome in complex with polyphenylalanyl-tRNA(Phe) was prepared as a target of tmRNA. A peptidyl transfer reaction from polyphenylalanyl-tRNA(Phe) to alanyl-tmRNA was observed in an SmpB-dependent manner. The next peptidyl transfer to aminoacyl-tRNA occurred specifically to the putative resume codon for the tag-peptide, which was confirmed by introducing a mutation in the codon. Thus, the in vitro systems developed in this study are useful to investigate the early steps of trans-translation. Using these in vitro systems, we investigated the function of ribosomal protein S1, which has been believed to play a role in trans-translation. Although T. thermophilus S1 tightly bound to tmRNA, as in the case of Escherichia coli S1, it had little or no effect on the early steps of trans-translation.
