Cloning of thioredoxin h reductase and characterization of the thioredoxin reductase-thioredoxin h system from wheat.
Thioredoxins h are ubiquitous proteins reduced by NADPH- thioredoxin reductase (NTR). They are able to reduce disulphides in target proteins. In monocots, thioredoxins h accumulate at high level in seeds and show a predominant localization in the nucleus of seed cells. These results suggest that the NTR-thioredoxin h system probably plays an important role in seed physiology. To date, the study...
متن کاملThe thioredoxin-thioredoxin reductase system: over-expression in human cancer.
Redox control has emerged as a fundamental biological control mechanism. One of the major redox control systems is the thioredoxin system comprised of thioredoxin (TRX) and thioredoxin reductase (TR). Together they form a powerful system involved in many central intracellular and extracellular processes including cell proliferation, the redox regulation of gene expression and signal transductio...
متن کاملThioredoxin-thioredoxin reductase--a system that has come of age.
Recent publications make it evident that the thioredoxin± thioredoxin reductase system has come of age. The four minireviews presented here attempt to put this field in perspective. The system was first recognized in the early 1960s as the reductant of methionine sulfoxide and PAPS (3 0-phosphoadenosine-5 0-phosphosulfate) in yeast and of ribonucleotides in Escherichia coli [1±3]. It became cle...
متن کاملCharacterization of a thioredoxin-thioredoxin reductase system from the hyperthermophilic bacterium Thermotoga maritima.
A thioredoxin reductase and a thioredoxin were purified to homogeneity from a cell extract of Thermotoga maritima. The thioredoxin reductase was a homodimeric flavin adenine dinucleotide (FAD)-containing protein with a subunit of 37 kDa estimated using SDS-PAGE, which was identified to be TM0869. The amino acid sequence of the enzyme showed high identities and similarities to those of typical b...
متن کاملIdentification of NADPH-thioredoxin reductase system in Euglena gracillis.
Euglena gracilis contains a protein system which can utilize the reducing power of NADPH in the ribonucleotide reductase-catalyzed reduction of CTP. The proteins required for this reaction are a flavoprotien with a molecular weight of approximately 185,000 which is functionally similar to thioredoxin reductase (NADPH), EC 1.6.4.5, and another protein (Protein I) whose function in the reaction i...
