Rapid Screening of Bacterial Chemoeffectors of Pseudomonas parafulva Using a CheA ATPase Activity‐Based Assay

Environmental Microbiology, Volume 28, Issue 9, September 2026.
We present a scalable, cell‐free, and straightforward NADH‐coupled CheA ATPase assay for quickly screening potential bacterial chemoeffectors and integrate it into a pipeline to identify both the chemoeffectors and their corresponding chemoreceptors in Pseudomonas parafulva, enabling systematic exploration of chemotactic sensing.

Molecular descriptor driven QSPR modeling of Papp, TEER and Efflux Ratio from Caco‐2 cells using machine learning for various phytochemicals

Journal of the Science of Food and Agriculture, Volume 106, Issue 11, Page 6606-6616, 30 August 2026.
Abstract BACKGROUND The present study aimed to develop and validate quantitative structure–property relationship (QSPR) models for predicting permeability related bioavailability indicators including apparent permeability (Papp), trans‐epithelial electrical resistance (TEER) and efflux ratio (ER) based on molecular descriptors (n = 5003) of 83 ...

Ecological function of phenazine in soil

Nature Microbiology
Phenazines, antimicrobial secondary metabolites, inhibit Gram-positive bacteria by targeting topoisomerase IV, but Bacillus cohabiting with phenazine-producing Pseudomonas can evolve resistance, enabling synergism for agricultural biocontrol.

Interplay between orfamides, sessilins and phenazines in the control of Rhizoctonia diseases by Pseudomonas sp CMR12a

, 2015
We investigated the role of phenazines and cyclic lipopeptides (CLPs) (orfamides and sessilins), antagonistic metabolites produced by Pseudomonas sp. CMR12a, in the biological control of damping-off disease on Chinese cabbage (Brassica chinensis) caused ...

Inhibition of Photophosphorylation by Phenazine Methosulfate

Journal of Biological Chemistry, 1967
Phenazine methosulfate was shown to be a competitive inhibitor of H+ in light-induced H+ transport as well as a competitive inhibitor of orthophosphate in photophosphorylation. Similarly, H+, NH4+, and Pi in the presence of adenosine diphosphate were shown to inhibit competitively light-induced binding of phenazine methosulfate to chloroplasts. Pi, in

Phenazines Regulate Nap-Dependent Denitrification in Pseudomonas aeruginosa Biofilms

, 2018
Microbes in biofilms face the challenge of substrate limitation. In particular, oxygen often becomes limited for cells inPseudomonas aeruginosabiofilms growing in the laboratory or during host colonization.
