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

Small lipases of Bacillus species, such as LipA from Bacillus subtilis, have a high potential for industrial applications. Recent studies showed that deletion of six AT-rich islands from the B. subtilis genome results in reduced amounts of extracellular LipA. Here we demonstrate that the reduced LipA levels are due to the absence of four genes, skfABCD, located in the prophage 1 region. Intact skfABCD genes are required not only for LipA production at wild-type levels by B. subtilis 168 but also under conditions of LipA overproduction. Notably, SkfA has bactericidal activity and, probably, requires the SkfB to SkfD proteins for its production. The present results show that LipA is more prone to proteolytic degradation in the absence of SkfA and that high-level LipA production can be improved significantly by employing multiple protease-deficient B. subtilis strains. In conclusion, our findings imply that SkfA protects LipA, directly or indirectly, against proteolytic degradation. Conceivably, SkfA could act as a modulator in LipA folding or as a protease inhibitor.
