The primary function of Thioredoxin (Trx) is the reduction of oxidized cysteine residues and the cleavage of disulfide bonds. Multiple in vitro substrates for thioredoxin have been identified, including ribonuclease, choriogonadotropins, coagulation factors, glucocorticoid receptor, and insulin. Reduction of insulin is classically used as an activity test. The thioredoxins are maintained in their reduced state by the flavoenzyme thioredoxin reductase, in a NADPH-dependent reaction… WebApr 15, 2024 · B. subtilis YtpP (Uniprot: O34357) is a thioredoxin-like protein with a molecular mass of 12.6 kDa and 107 amino acids, which contains 3 cysteine residues …
