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

Lysins are a class of hydrolytic enzymes used by bacteriophages to target and cleave the peptidoglycan of bacterial cell walls during their lytic cycle. The lysins from bacteriophages that infect Gram-positive bacteria are typically monomeric and consist of one or two catalytic domains (CD) and a cell binding domain (CBD). However, multimeric lysins encoded by a single gene have also been reported, among which Lys170 from enterococcal phage F170/08 was one of the first identified. Here, we determined the crystal structure of Lys170 CBD at 1.40 Å resolution. The structure reveals that Lys170 CBDs assemble into a tetrameric functional unit and that each monomer folds into a three-stranded β-sheet core capped on each side by an α-helix. In addition, we identified key residues of Lys170 CBD involved in host cell binding. Our work provides a basis for designing highly efficient lysins targeting Enterococcus faecalis.
