WebOxidation of the thiol functional group in cysteine (Cys-SH) to sulfenic (Cys-SOH), sulfinic (Cys-SO2H) and sulfonic acids (Cys-SO3H) is emerging as an important post-translational... WebThe active site cysteine (Cys51) is oxidized to cysteine sulfenic acid (Cys51-SOH) when a peroxide is reduced. Because Cys51-SOH is unstable, it forms a disulfide with Cys172-SH which comes from other subunit of the homodimer. The disulfide is then reduced back to the Prx … More Product Information Order Now SPECIFICATIONS ORDER …
