Cultivation at high osmotic pressure confers ubiquinone 8-independent protection of respiration on Escherichia coli.

The Journal of biological chemistry - 24 Jan 2020

Tempelhagen Laura, Ayer Anita, Culham Doreen E, Stocker Roland, Wood Janet M

Abstract excerpt

Ubiquinone 8 (coenzyme Q8 or Q8) mediates electron transfer within the aerobic respiratory chain, mitigates oxidative stress, and contributes to gene expression in Escherichia coli In addition, Q8 was proposed to confer bacterial osmotolerance by accumulating during growth at high osmotic pressure and altering membrane stability. The osmolyte trehalose and membrane lipid cardiolipin accumulate in E. coli cells...
