The catalytic Cys groups in thiol have lower pKa values of 5.57.4, which in turn act as a H 2 O 2 -sensing center and react with H 2 O 2 under physiological conditions ( 2 O 2 level and forms an inter or intramolecular disulfide bond (SS), sulfenic acid (SOH), sulfinic acid (SO 2 H), and sulfonic acid (SO 3 H), which alters the structure, activity, and interactions of different proteins and enzymes and ultimately changes their localization and regulates the metabolism and physiology of plants
