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 hallmark of glucokinase (GCK), which catalyzes the phosphorylation of glucose during glycolysis, is its kinetic cooperativity, whose understanding at atomic detail has remained open since its discovery over 40 years ago. Herein, by using kinetic CPMG NMR spectroscopic data for 17 isoleucine side chains distributed over all parts of GCK, we show that the origin of kinetic cooperativity is rooted in intramolecular protein dynamics. Residues of glucose-free GCK located in the small domain displayed distinct exchange behavior involving multiple conformers that are substantially populated (p>17 %) with a kex  value of 509±51 s(-1) , whereas in the glucose-bound form these exchange processes were quenched. This exchange behavior directly competes with the enzymatic turnover rate at physiological glucose concentrations, thereby generating the sigmoidal rate dependence that defines kinetic cooperativity.
