WebFor sulfur this over-oxidized form (sulfinic; RSO2H) cannot be reduced. For the enzyme this means that use of selenium confers protection from oxidative stress. If the enzyme is oxidized at a selenocysteine (Sec) residue and made inactive, exogenous thiol can convert it from the inactive Sec-SeO2H form into the active Sec-SeH form of the enzyme. 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 ...
