Webthioredoxin A and the target protein domain of interest re-stores the activity of a Gal4 transcription factor and allows the growth of yeast cells under selection. Several examples have been described in which aptamers were used to interfere with specific protein interactions in vivo and thus elicit distinct cellular phenotypes (22–28). 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 (Cys 28, Cys 31, and Cys 62). It has a signature thioredoxin fold and a CXXC motif with unique amino acid residues flanking the two cysteines (CPDC—Figure 4D).
WebDec 10, 2008 · Thioredoxin’s role to maintain the reduced form of HMGB1The concentration of thioredoxin in eukaryotic cells is believed to be 1–20 μM [9]. Our observed value of k Trx (3.0 M −1 s −1) for the Cys22–Cys44 disulfide bond suggests that it takes as long as 6 h for 10 μM thioredoxin to reduce 50% of the oxidized HMGB1. This reduction is ...
