Elucidation of the hetero-dimeric binding activity of LasR and RhlR proteins with the promoter DNA and the role of a specific Phe residue during the biosynthesis of HCN synthase from opportunistic pathogen Pseudomonas aeruginosa.

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.
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
Pseudomonas aeruginosa is an opportunistic human pathogen. It causes secondary infections in patients suffering from cancer and other immunological disorders. The pathogenicity of the organism is dependent on the ability of the organism to code for hydrogen cyanide (HCN), the synthesis of which is mediated by HCN synthase enzyme. HCN synthase is encoded by hcnABC operon. The transcription of the operon is controlled by a complex interplay between the proteins LasR and RhlR. Till date, there is no report that deals with the binding interactions of the RhlR-LasR heterodimer with the promoter DNA region of the hcnABC operon. We, for the first time, tried to analyse the binding modes of the RhlR-LasR heterodimer with the promoter DNA regions. From our work, we could predict the importance of a specific amino acid residue Phe214 from RhlR which might be considered to have the desired specificity to bind to the promoter DNA. Therefore, the amino acid Phe214 may be targeted to develop suitable ligands to eradicate the spread of secondary infections by Pseudomonas aeruginosa.
