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

The analysis of binding interactions between small molecules and biopolymers is important for understanding biological processes. While fluorescence correlation spectroscopy (FCS) requires fluorescence labeling on the small molecule, which often interferes with binding, in microscale thermophoresis (MST) the label can be placed on the biopolymer. Ribozymes have not been analyzed by MST so far. The Diels-Alderase ribozyme (DAse) is a true catalyst, facilitating the Diels-Alder reaction between two free small substrates, anthracene dienes, and maleimide dienophiles. Despite high efforts, the determination of the dissociation constant (KD) of maleimide dienophiles to the DAse by FCS has been unsuccessful. Here, we determined the binding interactions of the DAse to its substrates and the Diels-Alder product using MST. The results supported a positive cooperativity for substrate binding to the DAse. By varying the temperature, we furthermore studied the thermodynamics of dienophile dissociation. The entropic contribution was found to be the energetic driving force for the binding of the dienophile to the DAse.
