(1) simple disulfide exchange with GSSG granted that GSSG is sufficiently concentrated (2GSH/GSSG is ~1), (2) S is oxidized by H 2 O 2 generating a sulfenic acid (SOH) which, due to its very low pKa, can ionize and rapidly react with reduced glutathione (GSH), and (3) S forms a thiyl radical which then interacts with GSH forming a thiyl radical glutathionyl intermediate which then interacts with O 2 to form PSSG (Mailloux et al., 2013a)
