The mitochondrial respiratory complex I is a target for 15-deoxy-Δ12,14-prostaglandin J2 action

Journal of Lipid Research, 2005
The prostaglandin J2 derivative 15-deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2) is a very active compound with important effects on inflammation, apoptosis, and cell growth processes.

Impairment of respiratory chain under nutrient deficiencies in plants: does it play a role in the regulation of iron and sulfur responsive genes?

Frontiers in Plant Science, 2016
Plant production and plant product quality strongly depends on the availability of mineral nutrients. Among them, sulfur (S) and iron (Fe) play a central role, as they are needed for many proteins of the respiratory chain.

A Proteomic Analysis Indicates That Oxidative Stress Is the Common Feature Triggering Antibiotic Production in Streptomyces coelicolor and in the pptA Mutant of Streptomyces lividans

Frontiers in Microbiology, 2022
In most Streptomyces species, antibiotic production is triggered in phosphate limitation and repressed in phosphate proficiency. However, the model strain, Streptomyces coelicolor, escapes this general rule and produces actinorhoddin (ACT), a polyketide ...

Phenotypic effects of dietary stress in combination with a respiratory chain bypass in mice

Physiological Reports, 2019
The alternative oxidase (AOX) from Ciona intestinalis was previously shown to be expressible in mice and to cause no physiological disturbance under unstressed conditions.

Natural Mitochondria Targeting Substances and Their Effect on Cellular Antioxidant System as a Potential Benefit in Mitochondrial Medicine for Prevention and Remediation of Mitochondrial Dysfunctions

Current Issues in Molecular Biology, 2023
Based on the knowledge that many diseases are caused by defects in the metabolism of the cells and, in particular, in defects of the mitochondria, mitochondrial medicine starts precisely at this point.

Respiratory Chain

, 2022
Mitochondria is a rod-shaped organelle with a diameter of 1 micrometer that evolved at least 2000 million years back. The endosymbiotic hypothesis suggests that mitochondria are descended from specialized bacteria (probably alpha proteobacteria) that acquired an oxygen utilizing respiratory chain.

Composition and Stability of the Oxidative Phosphorylation System in the Halophile Plant Cakile maritima

Frontiers in Plant Science, 2019
Mitochondria play a central role in the energy metabolism of plants. At the same time, they provide energy for plant stress responses. We here report a first view on the mitochondrial Oxidative Phosphorylation (OXPHOS) system of the halophile (salt ...

Involvement of the cbb₃-Type Terminal Oxidase in Growth Competition of Bacteria, Biofilm Formation, and in Switching between Denitrification and Aerobic Respiration

Microorganisms, 2020
Paracoccus denitrificans has a branched electron transport chain with three terminal oxidases transferring electrons to molecular oxygen, namely aa3-type and cbb3-type cytochrome c oxidases and ba3-type ubiquinol oxidase. In the present study, we focused

Energy Conservation in the Acetogenic Bacterium Clostridium aceticum

Microorganisms, 2021
In times of global warming caused by the extensive use of fossil fuels, the need to capture gaseous carbon compounds is growing bigger. Several groups of microorganisms can fix the greenhouse gas CO2.
