Distribution of redox modification occupancy under physiological conditions. (A) The occupancy for both SSG (upper left, averages around 4.0%) and total oxidation (lower left, averages around 11.9%) spans a broad range, and SSG is a major form of reversible redox modifications constituting 31.9% of total oxidation on average (right). (B) PTM occupancies for selected protein Cys sites that displayed high occupancy of total oxidation.
