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

Microcin J25 (MccJ25) is a 21-residue plasmid-encoded ribosomally synthesized lariat-protoknot antibacterial peptide that targets bacterial RNA polymerase. MccJ25 consists of an 8-residue cycle followed by a 13-residue tail that loops back and threads through the cycle. We have performed systematic mutational scanning of MccJ25, constructing and analyzing more than 380 singly substituted derivatives of MccJ25. The results define residues important for production of MccJ25 (comprising synthesis of MccJ25 precursor, processing of MccJ25 precursor, export of mature MccJ25, and stability of mature MccJ25), inhibition of RNA polymerase, and inhibition of bacterial growth. The results show that only a small number of residues (three in the cycle and one in the threaded segment of the tail) are important for MccJ25 production. The results further show that only a small number of additional residues (two in the cycle and four in the threaded segment of the tail) are important for inhibition of transcription. The results open the way for design and construction of more potent MccJ25-based inhibitors of bacterial growth.
