Redox-dependent lipophilicity of phenazine metabolites is modulated by intramolecular hydrogen bonds and controls their biological distribution

Korbinian O. Thalhammer, Matthew Scurria, Jinyang Li, Inês Trindade, Osvaldo Gutiérrez, Stuart J. Conway, Dianne K. Newman

This study measures the redox-dependent lipophilicity of phenazines and shows how their redox state affects retention in bacterial cells.

Nitric oxide tunes secreted metabolite bioactivity

Zachery R. Lonergan, Sarah L. Weisflog, Matthew Scurria, Jinyang Li, Korbinian O. Thalhammer, Osvaldo Gutiérrez, Stuart J. Conway, Dianne K. Newman

This study shows nitric oxide modifies secreted metabolites' activity, reducing their antibiotic effects and causing toxicity to the producing bacteria.
