Peroxiredoxin(Prx/Prdx)is a highly conserved antioxidant enzyme family discovered in recent years,which is involved in maintaining the balance of intracellular reactive oxygen species.Prx is distributed in all organisms,including prokaryotes,eukaryotes,and even archaea.A large number of studies have shown that they play an important role in antioxidant,signal transduction,carcinogenesis,immune response,and other aspects in recent years.In this paper,the classification,catalytic mechanism and mediated functions of Prx family were briefly reviewed,and it was pointed out that the relevant mechanism of action needs further study,in order to provide some references for the research of Prx family.
