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

Linker and deletion mutagenesis and gene fusions were used to probe the possible domain structure of the dodecameric outer membrane secretin PulD from the pullulanase secretion pathway of Klebsiella oxytoca. Insertions of 24 amino acids close to or within strongly predicted and highly conserved amphipathic beta strands in the C-terminal half of the polypeptide (the beta domain) abolished sodium dodecyl sulfate (SDS)-resistant multimer formation that is characteristic of this protein, whereas insertions elsewhere generally had less dramatic effects on multimer formation. However, the beta domain alone did not form SDS-resistant multimers unless part of the N-terminal region of the protein (the N domain) was produced in trans. All of the insertions except one, close to the C terminus of the protein, abolished function. The N domain alone was highly unstable and did not form SDS-resistant multimers even when the beta domain was present in trans. We conclude that the beta domain is a major determinant of multimer stability and that the N domain contributes to multimer formation. The entire or part of the N domain of PulD could be replaced by the corresponding region of the OutD secretin from the pectate lyase secretion pathway of Erwinia chrysanthemi without abolishing pullulanase secretion. This suggests that the N domain of PulD is not involved in substrate recognition, contrary to the role proposed for the N domain of OutD, which binds specifically to pectate lyase secreted by E. chrysanthemi (V. E. Shevchik, J. Robert-Badouy, and G. Condemine, EMBO J. 16:3007-3016, 1997).
