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

The polymerization of peptidoglycan is the result of two types of enzymatic activities: transglycosylation, the formation of linear glycan chains, and transpeptidation, the formation of peptide cross-bridges between the glycan strands. Staphylococcus aureus has four penicillin binding proteins (PBP1 to PBP4) with transpeptidation activity, one of which, PBP2, is a bifunctional enzyme that is also capable of catalyzing transglycosylation reactions. Additionally, two monofunctional transglycosylases have been reported in S. aureus: MGT, which has been shown to have in vitro transglycosylase activity, and a second putative transglycosylase, SgtA, identified only by sequence analysis. We have now shown that purified SgtA has in vitro transglycosylase activity and that both MGT and SgtA are not essential in S. aureus. However, in the absence of PBP2 transglycosylase activity, MGT but not SgtA becomes essential for cell viability. This indicates that S. aureus cells require one transglycosylase for survival, either PBP2 or MGT, both of which can act as the sole synthetic transglycosylase for cell wall synthesis. We have also shown that both MGT and SgtA interact with PBP2 and other enzymes involved in cell wall synthesis in a bacterial two-hybrid assay, suggesting that these enzymes may work in collaboration as part of a larger, as-yet-uncharacterized cell wall-synthetic complex.
