WebAbcam’s Thioredoxin Reductase (TrxR) Assay Kit provides a convenient colorimetric assay for detecting TrxR activity in various samples. In the assay, TrxR catalyzes the reduction … Cancer treatment Since the activity of this enzyme is essential for cell growth and survival, it is a good target for anti-tumor therapy. Furthermore, the enzyme is upregulated in several types of cancer, including malignant mesothelioma. For example, motexafin gadolinium (MGd) is a new chemotherapeutic … See more Thioredoxin reductases (TR, TrxR) (EC 1.8.1.9) are enzymes that reduce thioredoxin (Trx). Two classes of thioredoxin reductase have been identified: one class in bacteria and some eukaryotes and one … See more Two classes of thioredoxin reductase have evolved independently: • A high molecular weight (MW = ~55,000) type containing a selenocysteine residue in its active site has been identified in higher eukaryotes including humans. This TxR is related to See more E. coli In E. coli ThxR the spatial orientation of the FAD and NADPH domains are such that the redox-active rings of FAD and NADPH are not in close … See more • Thioredoxin+Reductase+(NADPH) at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more Thioredoxin reductases are enzymes that catalyze the reduction of thioredoxin and hence they are a central component in the thioredoxin system. … See more E. coli In E. coli ThxR there are two binding domains, one for FAD and another for NADPH. The connection between these two domains is a … See more Thioredoxin reductase can be quantified by various methods such as the DTNB assay using Ellman's reagent. The disulfide-based TRFS series of fluorescent probes have shown selective detection of TrxR. Mafireyi synthesized the first diselenide probe … See more
