Escherichia coli ... TRXB(949054)

Descrizione generale

Thioredoxin reductase (TrxR) is encoded by TRXB gene. TrxR is one of the member of flavoprotein family of pyridine nucleotide-disulphide oxidoreductases, which also includes lipoamide dehydrogenase, glutathione reductase and mercuric ion reductase. Escherichia coli TrxR is a 70-kDa homodimeric flavoprotein, each monomer of this protein contains a FAD prosthetic group, an NADPH domain and an active site with redox-active disulphide. The catalytic site (-Cys-Ala-Thr-Cys-) in Escherichia coli TrxB is localized on the NADPH domain, whereas in humans TrxB catalytic site (-Cys-Val-Asn-Val-Gly-Cys-) is part of the FAD domain.

Azioni biochim/fisiol

Thioredoxin reductase (TRXB) catalyzes the reduction of oxidized thioredoxin using nicotinamide adenine dinucleotide phosphate (NADPH). In thioredoxin pathway, this reduced thioredoxin reduce disulfide bonds in proteins localized in the cytoplasm and is implicated in the recycling of an essential enzyme ribonucleotide reductase. TrxR is essentially involved in protection against oxidation stress, cell growth and transformation, and the recycling of ascorbate from its oxidized form.

Thioredoxin, thioredoxin reductase and NADPH, the thioredoxin system, is ubiquitous from Archea to man. Thioredoxins, with a dithiol/disulfide active site (CGPC) are the major cellular protein disulfide reductases; they therefore also serve as electron donors for enzymes such as ribonucleotide
