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

Microcin E492-producing bacteria secrete both unmodified and posttranslationally modified microcins. The modification consists of a C-glucosylated linear trimer of N-(2,3-dihydroxybenzoyl)-l-serine, a catecholate siderophore related to salmochelins and enterobactin. We show here that repression of enterobactin biosynthesis inhibits the acquisition of microcin E492 posttranslational modification, as monitored by high-performance liquid chromatography and mass spectrometry. Furthermore, exogenous enterobactin restored the production of posttranslationally modified microcin in a bacterial strain deficient in enterobactin synthesis. We thus concluded that enterobactin serves as a precursor for the synthesis of the posttranslationally modified microcin and that the unmodified microcin is an incompletely processed form of mature microcin E492. Gene disruption experiments showed that MceC and MceD, two enzymes encoded by the mceABCDEFGHIJ gene cluster, are involved in the synthesis of the microcin E492 posttranslational modification, as followed by mass spectrometry. Genes homologous to iroB and iroD, required for the conversion (linearization and C-glycosylation) of enterobactin into salmochelins, efficiently complemented mceC and mceD, respectively. Based on our results, a model is proposed for the biosynthesis of the mature siderophore-carrying peptide.
