PPAR , a member of the nuclear receptor superfamily, and thioredoxin, a critical redox-regulator in cells, were found to form a negative feedback loop, which autoregulates transcriptional activity of PPAR . Thioredoxin was identified as a target gene of PPAR . Activation of PPAR leads to increase of thioredoxin expression as well as its translocation from cytoplasm to nucleus, whereas ectopic o...
Structural studies show that enzymes have a limited number of unique folds, although structurally related evolved to perform large variety functions. In this review, we focused on containing the low molecular weight thioredoxin reductase (low Mr TrxR) fold. This fold consists two domains, both three-layer ??? sandwich Rossmann-like fold, serving as flavin adenine dinucleotide (FAD) and, in most...
AhpF of Salmonella typhimurium, the flavoprotein reductase required for catalytic turnover of AhpC with hydroperoxide substrates in the alkyl hydroperoxide reductase system, is a 57 kDa protein with homology to thioredoxin reductase (TrR) from Escherichia coli. Like TrR, AhpF employs tightly bound FAD and redox-active disulfide center(s) in catalyzing electron transfer from reduced pyridine nuc...
BACKGROUND Excessive formation of reactive oxygen species contributes to tissue injury and functional deterioration after myocardial ischemia/reperfusion. Especially, mitochondrial reactive oxygen species are capable of opening the mitochondrial permeability transition pore, a harmful event in cardiac ischemia/reperfusion. Thioredoxins are key players in the cardiac defense against oxidative st...
Redox control has emerged as a fundamental biological control mechanism. One of the major redox control systems is the thioredoxin system comprised of thioredoxin (TRX) and thioredoxin reductase (TR). Together they form a powerful system involved in many central intracellular and extracellular processes including cell proliferation, the redox regulation of gene expression and signal transductio...
The aim of the present study is to assess the rate of protein disulphide formation and the activity of NADPH-dependent thioredoxin and glutaredoxin systems, responsible for the reverse reduction of protein and mixed protein-glutathione disulphides, in embryogenic suspension cultures of Dactylis glomerata, subjected to salt stress. Two concentrations of NaCl previously established as enhancing (...
