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

Promiscuity, or selectivity on a spectrum, is an encoded feature in biomolecular anion recognition. To unravel the molecular drivers of promiscuous anion recognition, we have employed a comprehensive approach - spanning experiment and theory - with the Staphylococcus carnosus nitrate regulatory element A (ScNreA) as a model. Thermodynamic analysis reveals that ScNreA complexation with native nitrate and nitrite or non-native iodide is an exothermic process. Further deconvolution of the association and dissociation kinetics for each anion reveals that the release event can be limiting, in turn, giving rise to the observed selectivity: nitrate > iodide > nitrite. These conclusions are supplemented with molecular dynamics simulations that capture an entry and exit pathway coupled to subtle global protein motions unique to each anion. Taken together, our data point to how structural plasticity of the binding pocket controls the relative promiscuity of ScNreA to guarantee physiological nitrate sensing.
