WebIn P. aeruginosa PAO1, three cytoplasmic thioredoxins have been identified. An unusual thioredoxin (Patrx2) (108 amino acids) encoded by the PA2694 gene, is identified as a new thioredoxin-like protein based on sequence homology. Thioredoxin is a ubiquitous protein, which serves as a general protein disulfide oxidoreductase. WebThe thioredoxin system (TRX, TRX reductase, and NADPH) reduces oxidized cysteine groups on proteins through an interaction with the redox-active center of TRX (cys-gly-pro-cys) to form a disulfide bond, which in turn can be reduced by TRX reductase and NADPH. 81 The enzyme regenerates reduced thioredoxin, which serves as reducing equivalent ...
Thioredoxin is a class of small redox proteins known to be present in all organisms. It plays a role in many important biological processes, including redox signaling. In humans, thioredoxins are encoded by TXN and TXN2 genes.
