Peroxiredoxin 3 (Prx3), Human

Peroxiredoxin 3 (Prx3) is a crucial antioxidant enzyme primarily found in the mitochondria, where it plays a vital role in protecting cells from oxidative stress. It belongs to the 2-Cys peroxiredoxin family, characterized by two key cysteine residues essential for its function. Prx3 reduces harmful hydrogen peroxide (H₂O₂) and organic hydroperoxides to water and alcohol, respectively, thereby maintaining cellular redox balance and influencing processes like apoptosis. Its unique mitochondrial localization makes it a key player in managing reactive oxygen species (ROS) produced during cellular respiration.
