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 flavoprotein d-amino acid oxidase has long served as a paradigm for understanding the mechanism of oxidation of amino acids by flavoproteins. Recently, a mutant d-amino acid oxidase (Y228L/R283G) that catalyzed the oxidation of amines rather than amino acids was described [Yasukawa, K., et al. (2014) Angew. Chem., Int. Ed. 53, 4428-4431]. We describe here the use of pH and kinetic isotope effects with (R)-α-methylbenzylamine as a substrate to determine whether the mutant enzyme utilizes the same catalytic mechanism as the wild-type enzyme. The effects of pH on the steady-state and rapid-reaction kinetics establish that the neutral amine is the substrate, while an active-site residue, likely Tyr224, must be uncharged for productive binding. There is no solvent isotope effect on the k
