WebUnder higher oxidative stress the sulfenic acid undergo further oxidation to sulfinic acid (Cys-SO2H), which can subsequently be reduced. The sulfinic acid can be hyperoxidized to sulfonic acid (Cys-SO3H), whose reduction is irreversible. Formation of sulfenic acids can have a role in sensing oxidative stress, signal transduction, modulating ... WebJul 10, 2024 · DAQ has been shown to affect the cell’s ability to sequester ROS by reacting with Cys-106 of the neuroprotective protein DJ-1 (van Laar et al., 2009; Girotto et al., 2012). In nigral neurons not affected by PD, DJ-1 is mostly localized to the cytoplasm, however, when exposed to high levels of ROS, it is oxidized to the Cys-SO2H form and ...
