Sulfite reductase and thioredoxin in oxidative stress responses of methanogenic archaea
… that certain methanogens use an unusual sulfite reductase, named F420-dependent sulfite reductase (Fsr), for the detoxification of SO32- that is produced outside the cell from a reaction between oxygen and sulfide. This reaction occurred during early oxygenation of Earth and continues to …

Understanding the Effects of Higher-Order Assembly on the Structure of Sulfite Reductase
Oxidoreductase enzyme complexes are one of the known biomolecular machines, which play a crucial role in cellular biochemistry including metabolic, signaling, and electron transport pathways. In these complexes, individual subunits can oligomerize to form homo-multimers or hetero-multimers and can …

Developing assays to study and screen engineered Escherichia coli NADPH-dependent sulfite reductase
… that participate in these reactions (e.g., oxidoreductases) through protein engineering. However, successful enzyme engineering studies depend on appropriate assays to evaluate and characterize the desired variants. The Escherichia coli NADPH-dependent sulfite reductase is a heterododecameric …

Quantifying the expression of dissimilatory sulfite reductase as a metric for sulfate reduction rates
… whether the gene expression of dissimilatory sulfite reductase (dsr mRNA), a critical enzyme in the sulfate reduction pathway, can serve as an indicator of the rate of sulfate reduction in natural systems. We grew Desulfovibrio vulgaris in fed-batch reactors under electron-donor limiting …

The Role Of Cardiolipin In Iron Homeostasis And Glutathione Metabolism
… dehydrogenase, and ubiquinol-cytochrome c oxidoreductase), as well as cytosolic Fe-S enzymes (sulfite reductase and isopropylmalate isomerase). Increased expression of ATM1 or YAP1, which encode proteins involved in the export of mitochondrial generated Fe-S co-factors to the cytosol and a …

Novel Electron Transfer Systems in Hyperthermophilic Methanogenic and Anaerobic Methanotrophic Archaea: F420-dependent Nitrite Reductase and [Fe-S] Cluster Assembling Thioredoxin
… survival strategies, an F420-dependent sulfite reductase (Fsr), deazaflavin-dependent flavin-containing thioredoxin reductase (DFTR), and a thioredoxin (Trx) homolog with a new function. These proteins are involved in redox reactions, and the research presented here deals with the …

Microbial pathways of sulfur metabolism and colorectal cancer risk
… bacteria (SRB), dissimilatory sulfate reductase (pan-dsrA), Bilophila wadsworthia-specific dsrA, and 16S rRNA genes for Desulfobacter spp., Desulfovibrio spp., and Desulfotomaculum spp.. Bilophila wadsworthia-specific dsrA was more abundant in AA cases compared to AA controls (p<0.001). …
