Redox chemistry is a key feature of life. Oxidized substrates are reduced to synthesize functional molecules; reduced substrates are oxidized for energy supply. In addition, cells must fight against u...
Low levels of reactive oxygen and nitrogen species (ROS and RNS) produced by the mitochondrial respiratory chain and ROS and RNS from other sources act as redox signals by oxidizing thiols on specific...
The cellular glutathione redox buffer is assumed to be part of signal transduction pathways transmitting environmental signals during biotic and abiotic stress, and thus is essential for regulation of...
The Nrf2 transcription factor is more rapidly turned over in cells grown under homeostatic conditions than in those experiencing oxidative stress. The variable turnover of Nrf2 is accomplished through...
The circular dichroism (CD) spectra of 13 examples of high-potential iron-sulfur proteins (HiPIPs), a class of [4Fe-4S] ferredoxins, have been determined. In contrast to the proposal of Carter [Carter...
The study focused on the effects on various redox states of hemoglobin during NADPH: cytochrome P-450 reductase-catalyzed redox cycling of quinones and nitrocompounds. The following reactions involvin...
The use of lucigenin luminescence as a measure of ¿O-(2) has been questioned because lucigenin has been shown to be capable of mediating the production of O-(2). This being the case, lucigenin can si...
Sulphur metabolism in plants provides a wealth of natural products, including several chemically unusual substances, such as thiosulphinates, polysulphides and isothiocyanates. Many of these reactive ...
