Novel agents for the in-situ detection of cysteine oxidation states
... Cysteine (Cys-SH) readily undergoes oxidation by reactive oxygen species (ROS) to form sulfenic (Cys-OH), sulfinic (Cys-SO2H) and sulfonic (Cys-SO3H) acids. Thiol modifications of cysteine have been implicated as modulators of cellular processes and represent significant biological modifications tha ...
