Thiol antioxidant
WebAn important role for LMW thiols that predates the protection against oxidative stress is the detoxification of electrophiles, including epoxides, enones, and other sulfhydryl reactive agents. LMW thiols are nucleophiles able to react with electrophiles spontaneously or through catalysis by S -transferases, forming S -conjugates. WebJan 8, 2014 · The thioredoxin antioxidant system in the bacterium contains one TrxR, two Trxs (Trx1 and Trx2), and three major thiol peroxidases (BCP, Tpx, and AhpC). E. coli OxyR transcription factor regulates the expression of many antioxidant enzymes including AhpC, catalase, GR, Trx2, and Grx1.
