FNR-mediated regulation of bioluminescence and anaerobic respiration in the light-organ symbiont Vibrio fischeri [PDF]

, 2010
Vibrio fischeri induces both anaerobic respiration and bioluminescence during symbiotic infection. In many bacteria, the oxygen-sensitive regulator FNR activates anaerobic respiration, and a preliminary study using the light-generating lux genes from V ...

Crp and Arc system directly regulate the transcription of NADH dehydrogenase genes in Shewanella oneidensis nitrate and nitrite respiration

Microbiology Spectrum
NADH oxidation by NADH dehydrogenases (NDHs) is crucial for feeding respiratory quinone pool and maintaining the balance of NADH/NAD+. In the respiratory model organism Shewanella oneidensis, which possesses four NDHs, the longstanding notion had been ...

Warburg Effect, Glutamine, Succinate, Alanine, When Oxygen Matters

Biology, 2021
Cellular bioenergetics requires an intense ATP turnover that is increased further by hypermetabolic states caused by cancer growth or inflammation. Both are associated with metabolic alterations and, notably, enhancement of the Warburg effect (also known

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

FEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Catalase (KatA) plays a role in protection against anaerobic nitric oxide in Pseudomonas aeruginosa. [PDF]

PLoS ONE, 2014
Pseudomonas aeruginosa (PA) is a common bacterial pathogen, responsible for a high incidence of nosocomial and respiratory infections. KatA is the major catalase of PA that detoxifies hydrogen peroxide (H2O2), a reactive oxygen intermediate generated ...

Reforming Nitrate Metabolism for Enhancing L-Arginine Production in Corynebacterium crenatum Under Oxygen Limitation

Frontiers in Microbiology, 2022
Various amino acids are widely manufactured using engineered bacteria. It is crucial to keep the dissolved oxygen at a certain level during fermentation, but accompanied by many disadvantages, such as high energy consumption, reactive oxygen species, and

Degradation of BTEX by anaerobic bacteria: physiology and application [PDF]

, 2010
Pollution of the environment with aromatic hydrocarbons, such as benzene, toluene, ethylbenzene and xylene (so-called BTEX) is often observed. The cleanup of these toxic compounds has gained much attention in the last decades.

Engineered Cyanobacteria‐Hydrogel Microecological System for Oxygen Reprogramming Synergizes Immunomodulation With Anabolism in Osteoarthritis Therapy

Advanced Science, EarlyView.
An injectable cyanobacteria‐laden hydrogel enables light‐dependent oxygen metabolism engineering for osteoarthritis therapy. Photosynthetic oxygen release under red light irradiation suppresses synovial inflammation via HIF‐1α inhibition and M2 macrophage polarization, while respiratory oxygen consumption in darkness stabilizes chondrocyte HIF‐1α to ...
