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

Ribosomally synthesized and post-translationally modified peptides (RiPPs) are ubiquitous natural products. Bioactive RiPPs are produced from a precursor peptide, which is modified by enzymes. Usually, a single product is encoded in a precursor peptide. However, in cyanobactins and several other RiPP pathways, a single precursor peptide encodes multiple bioactive products flanking with recognition sequences known as "cassettes". The role of multiple cassettes in one peptide is mysterious, but in general their presence is a marker of biosynthetic plasticity. Here, we show that in cyanobactin biosynthesis the presence of multiple cassettes confers distributive enzyme processing to multiple steps of the pathway, a feature we propose to be a hallmark of multicassette RiPPs. TruD heterocyclase is stochastic and distributive. Although a canonical biosynthetic route is favored with certain substrates, every conceivable biosynthetic route is accepted. Together, these factors afford greater plasticity to the biosynthetic pathway by equalizing the processing of each cassette, enabling access to chemical diversity.
