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

Escherichia coli topoisomerase I (EcTopoI) is a type IA bacterial topoisomerase which is receiving large attention due to its potential application as novel target for antibacterial therapeutics. Nevertheless, a detailed knowledge of its mechanism of action at molecular level is to some extent lacking. This is partly due to the requirement of several factors (metal ions, nucleic acid) to the proper progress of the enzyme catalytic cycle. Additionally, each of them can differently affect the protein structure. Here we assess the role of the different components (DNA, metal ions, protein domains) in a dynamic environment as in solution by monitoring the catalytic as well as the structural properties of EcTopoI. Our results clearly indicated the interaction among these components as functionally relevant and underlined their mutual involvement. Some similarities with other enzymes of the same family emerged (for example DNA prevents divalent metal ions coordination at non selective binding sites). Interestingly, same interactions (C- and N-terminal domain interaction) appear to be peculiar of this bacterial topoisomerase which suggest they could be favorably exploited to the design of selective inhibitors for this class of enzyme.
