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

Heme d1, a vital tetrapyrrol involved in the denitrification processes is synthesized from its precursor molecule precorrin-2 in a chemical reaction catalysed by an S-adenosyl-L-methionine (SAM) dependent Methyltransferase (NirE). The NirE enzyme catalyses the transfer of a methyl group from the SAM to uroporphyrinogen III and serves as a novel potential drug target for the pharmaceutical industry. An important insight into the structure-activity relationships of NirE has been revealed by elucidating its crystal structure, but there is still no understanding about how conformational flexibility influences structure, cofactor and substrate binding by the enzyme as well as the structural effects of mutations of residues involved in binding and catalysis. In order to provide this missing but very important information we performed a comprehensive atomistic molecular dynamics study which revealed that i) the binding of the substrate contributes to the stabilization of the structure of the full complex; ii) conformational changes influence the orientation of the pyrrole rings in the substrate, iii) more open conformation of enzyme active site to accommodate the substrate as an outcome of conformational motions; and iv) the mutations of binding and active site residues lead to sensitive structural changes which influence binding and catalysis.
