The redox regulation mechanism responsible for efficient production of ATP under varying light conditions in photosynthetic organisms has now been unveiled. Researchers investigated the enzyme ...

However, the enzyme complexes without the redox loop or the β-hairpin domain did not show the redox-response, indicating that both regions were involved in the redox regulation mechanism.

Figure 1: Proposed mechanism for the proton-motive force generating redox loop by NarGHI and FdnGHI. The position of FS0, between the Mo-bisMGD and the FS1 cluster in NarH (edge-to-edge distances ...

Background Chronic inflammation and elevated reactive oxygen species are key contributors to hepatocellular carcinoma (HCC) ...

In redox reactions, electrons are transferred between molecules. Because electrons have a negative charge, this can cause the charge of the reactants to change, which is energetically demanding.

High-pressure pump–probe experiments reveal the mechanism of excited-state proton-coupled electron transfer and a shift from stepwise to concerted pathways. Nature Chemistry , 2025; DOI: 10.1038 ...

A group of researchers in Japan has revealed, for the first time, a mechanism for controlling the potential of an electron carrier protein in the redox reaction that all organisms need to obtain ...

The research group discovered the phenomenon of insulin resistance-like "Redox-stress Response Resistance (RRR)" in senescent cells, and revealed a new mechanism of PRDX2 hyperoxidation leading to ...

Argonne chemist Max Delferro, an author of the study, commented that "in this redox mechanism, our material takes its usual chemical routine and turns it on its head—instead of giving up a ...

The mechanism, Schmidt said, is a previously unknown tool that cells can use to protect their proteins from being irreversibly damaged by cellular processes called redox reactions, which are common ...
