Abstract:Oxidative stress is a highly common stress for cells, which targets proteins with oxidation of cysteine residues. The thioredoxin (Trx) system, which is a ubiquitous system for thiol- and protein-repair, is composed of a thioredoxin (TrxA) and a thioredoxin-reductase (TrxB). TrxAs reduce disulfide bonds of oxidized proteins and are then usually recycled by a single pleiotropic NAD(P)H-dependent TrxB (NTR). However, some Clostridia have also ferredoxin-dependent TrxBs. In this work, we first analyzed the compos… Show more
