1 · What the graph read from it

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.

2 · The registry

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

Bacterial ribonuclease P (RNase P) catalyzes the cleavage of 5' leader sequences from precursor tRNAs (pre-tRNAs). Previously, all known substrate nucleotide specificities in this system are derived from RNA-RNA interactions with the RNase P RNA subunit. Here, we demonstrate that pre-tRNA binding affinities for Bacillus subtilis and Escherichia coli RNase P are enhanced by sequence-specific contacts between the fourth pre-tRNA nucleotide on the 5' side of the cleavage site (N(-4)) and the RNase P protein (P protein) subunit. B. subtilis RNase P has a higher affinity for pre-tRNA with adenosine at N(-4), and this binding preference is amplified at physiological divalent ion concentrations. Measurements of pre-tRNA-containing adenosine analogs at N(-4) indicate that specificity arises from a combination of hydrogen bonding to the N6 exocyclic amine of adenosine and steric exclusion of the N2 amine of guanosine. Mutagenesis of B. subtilis P protein indicates that F20 and Y34 contribute to selectivity at N(-4). The hydroxyl group of Y34 enhances selectivity, likely by forming a hydrogen bond with the N(-4) nucleotide. The sequence preference of E. coli RNase P is diminished, showing a weak preference for adenosine and cytosine at N(-4), consistent with the substitution of Leu for Y34 in the E. coli P protein. This is the first identification of a sequence-specific contact between P protein and pre-tRNA that contributes to molecular recognition of RNase P. Additionally, sequence analyses reveal that a greater-than-expected fraction of pre-tRNAs from both E. coli and B. subtilis contains a nucleotide at N(-4) that enhances RNase P affinity. This observation suggests that specificity at N(-4) contributes to substrate recognition in vivo. Furthermore, bioinformatic analyses suggest that sequence-specific contacts between the protein subunit and the leader sequences of pre-tRNAs may be common in bacterial RNase P and may lead to species-specific substrate recognition.
