How Thioredoxin Dissociates Its Mixed Disulfide - PLOS

Thioredoxin reductases are enzymes that catalyze the reduction of thioredoxin and hence they are a central component in the thioredoxin system. Together with thioredoxin (Trx) and NADPH this system's most general description is as a system for reducing disulfide bonds in cells. Electrons are taken from NADPH via TrxR and are transferred to the active site of Trx, which goes on to reduce p… 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. WebTrx is reduced by the NADPH-dependent flavoenzyme thioredoxin reductase, and in turn reduces other proteins such as protein disulfide isomerase (PDI) by cysteine thiol-disulfide exchange. Trx has been reported to selectively activate the DNA binding of a number of transcription factors such as p53, NFkB, AP1 and glucocorticoid receptor ... strada downtown asheville
