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

Undecaprenyl pyrophosphate phosphatase (UppP), an integral membrane protein, catalyzes the dephosphorylation of undecaprenyl pyrophosphate to undecaprenyl phosphate, which is an essential carrier lipid in the bacterial cell wall synthesis. Sequence alignment reveals two consensus regions, containing glutamate-rich (E/Q)XXXE plus PGXSRSXXT motifs and a histidine residue, specific to the bacterial UppP enzymes. The predicted topological model suggests that both of these regions are localized near the aqueous interface of UppP and face the periplasm, implicating that its enzymatic function is on the outer side of the plasma membrane. The mutagenesis analysis demonstrates that most of the mutations (E17A/E21A, H30A, S173A, R174A, and T178A) within the consensus regions are completely inactive, indicating that the catalytic site of UppP is constituted by these two regions. Enzymatic analysis also shows an absolute requirement of magnesium or calcium ions in enzyme activity. The three-dimensional structural model and molecular dynamics simulation studies have shown a plausible structure of the catalytic site of UppP and thus provides insights into the molecular basis of the enzyme-substrate interaction in membrane bilayers.
