Systematic determination of disulfide bond reduction potentials reveals a nonequilibrium redox hierarchy in cyanobacteria.

Proceedings of the National Academy of Sciences of the United States of America 20260519 21

Disulfide bonds act as reversible switches that regulate cellular function in nearly all organisms. Their behavior is set by the midpoint potential (Em), yet Em is known for only a small number of sites, mostly in purified proteins studied away from their natural partners. We developed a mass-spectrometry workflow that measures Em directly from native cell lysates. By equilibrating proteins of the cyanobacterium Synechocystis sp. PCC 6 ...[more]

Changes in gene expression when the redox potential of steady state cultures of Staphylococcus aureus is lowered by addition of dithiothreitol

Project description:Staphylococcus aureus can survive in the low redox potential environment of the host cytosol. How low redox potential affects S. aureus USA300 Je2 was investigated by establishing aerobic steady state chemostat cultures and then perturbing the steady state by addition of the reducing agent dithiothreitol. These highly controlled steady state cultures allowed only one parameter (redox potential) changed. Dithiothreitol was used as a non-metabolizable reductant. Before and after perturbation samples were taken for gene expression profiling. Three independent biological replicates were analyzed.

Clostridium thermocellum DSM 1313 Transcriptional Responses to Redox Perturbation

Project description:Clostridium thermocellum is a promising CBP candidate organism capable of directly converting lignocellulosic biomass to ethanol. Low yields, productivities and growth inhibition prevent industrial deployment of this organism for commodity fuel production. Symptoms of potential redox imbalance such as incomplete substrate utilization, and fermentation products characteristic of overflow metabolism, have been observed during growth. This perceived redox imbalance may be in part responsible for the mentioned bioproductivity limitations. Toward better understanding the redox metabolism of C. thermocellum, we analyzed gene expression, using microarrays, during addition of two stress chemicals (methyl viologen and hydrogen peroxide) which we observed to change fermentation redox potential. High quality RNA was extracted from C. thermocellum grown on cellobiose in chemostat culture and exposed, separately, to methyl viologen and hydrogen peroxide. Transcriptome profiles were obtained at seven time points during actively growing fermentations, 3 minutes, 15 minutes, 35 minutes, 7 hours, 14 hours, 50 hours, and 60 hours after beginning exposure to each stressor. Exposure treatments were carried out in duplicate and reference/untreated samples were taken before and between treatments, after flushing of stressor chemicals and re-equilibration of growth conditions.

Redox Imbalance in COVID-19 Pathophysiology

Project description:The pathophysiologic significance of redox imbalance is unquestionable as numerous reports and topic reviews indicate alterations in redox parameters during corona virus disease 2019 (COVID-19). However, a more comprehensive understanding of redox-related parameters in the context of COVID-19-mediated inflammation and pathophysiology is required. COVID-19 subjects (n=64) and control subjects (n=19) were enrolled, and blood was drawn within 72 hours of diagnosis. Serum multiplex assay and buffy coat cell mRNA sequencing was performed. Oxidant/free radical (electron paramagnetic resonance (EPR) spectroscopy, nitrite-nitrate assay) and antioxidant (ferrous reducing ability of serum assay and high-performance liquid chromatography) were performed. Multivariate analyses were performed to evaluate potential of indicated parameters to predict clinical outcome. Significantly greater levels of multiple inflammatory and vascular markers were quantified in the subjects admitted to the ICU compared to non-ICU subjects. Gene set enrichment analyses indicated significant enhancement of oxidant related pathways and biochemical assays confirmed a significant increase in free radical production and uric acid reduction in COVID-19 subjects. Multivariate analyses confirmed a positive association between serum levels of VCAM-1, ICAM-1 and a negative association between the abundance of one electron oxidants (detected by ascorbate radical formation) and mortality in COVID subjects while IL-17c and TSLP levels predicted need for intensive care in COVID-19 subjects.

Impact of oxygen availability on the organelle-specific redox potentials and stress in recombinant protein producing Komagataella phaffii

Project description:The yeast Komagataella phaffii (syn. Pichia pastoris) is a highly effective and well-established host for the production of recombinant proteins. The redox balance of its secretory pathway, which is multi-organelle dependent, is of high importance for producing secretory proteins. Redox imbalance and oxidative stress an significantly influence protein folding and secretion. Glutathione serves as the main redox buffer of the cell and cellular redox conditions can be assessed through the status of the glutathione redox couple (GSH-GSSG). Previous research often focused on the redox potential of the endoplasmic reticulum (ER), where oxidative protein folding and disulfide bond formation occur. In this study, in vivo measurements of the glutathione redox potential were extended to different subcellular compartments by targeting genetically encoded redox sensitive fluorescent proteins (roGFPs) to the cytosol, ER, mitochondria and peroxisomes. Using these biosensors, the impact of oxygen availability on the redox potentials of the different organelles was investigated in non-producing and producing K. phaffii strains in glucose-limited chemostat cultures. It was found that the transition from normoxic to hypoxic conditions affected the redox potentials of all investigated organelles, while the exposure to hyperoxic conditions did not impact them. Also, as reported previously, hypoxic conditions led to increased recombinant protein secretion. Finally, transcriptome and proteome analyses provided novel insights into the short-term adaptation of the cells from normoxic to hypoxic conditions.
