The purified TrxA(CACC) and TrxA(CAC A) proteins were dark brown, in contrast to wild-type thioredoxin and TrxA(A ACC), which were colorless. The absorbance spectrum of the TrxA(CAC A) and TrxA(CACC) mutants showed peaks at 340, 412, and 452 nm and a shoulder at 560 nm, which is very similar to the iron-sulfur protein ferredoxin .However, periplasmic TrxA in a dsbA- strain was able to oxidize the alkaline phosphatase (PhoA) such that PhoA activity was only 22% of wild type levels. Further optimization identified a mutant, TrxA_G74S [50], that interacted better with DsbB [49], restoring PhoA activity to levels similar to wild type.trxA and trxC: trxB: Used to prevent oxidative damage from reactive nitrogen intermediates: St. John et al., 2001; Potamitou et al., 2002: Open in a separate window.

To construct the mutant strain ΔtrxA, primers TrxAKOF1/TrxAKOR1 and TrxAKOF2/TrxAKOR2 were used for the upstream and downstream PCR of trxA. The fusion PCR products amplified by primer pair TrxAKOF1/R2 were cloned into the pDM4 at the Bgl II site, in which a 1330 bp segment in-frame deletion was created, resulting in pDMTrxA.

The TrxA(CACA) mutant protein crystallized in the monoclinic P2 1 space group (Table 1 1).). This differs from wildtype TrxA, which crystallizes in the C2 space group (Holmgren et al. 1975; Katti et al. 1990). Though unusual, other thioredoxin mutants are known to crystallize in a space group different from that of the wild-type protein.

Purchase Recombinant Human CD20/MS4A1 Protein (TrxA Tag) online from Elabscience company with reasonable price and professional tech support.Nov 11, 1999 · Likewise, in FA113, TrxA expressed from the chromosome was present solely in the oxidized form (P.H.B., J. Qiu, and G.G., unpublished data). We examined the effect of high level expression of TrxA and TrxA mutant proteins with varying redox potentials on the folding of the more complex multidisulfide proteins, namely vtPA and tPA. To this end, lnqQ (structure gene of an LLB, lacticin Q) and trxA, an essential gene for T7 phage genome replication, were integrated in tandem into T7 phage genome using homologous recombination in Escherichia coli host strain. The recombinant lnqQ-T7 phage was isolated by a screening method using ΔtrxA host strain.Although TrxA is a cytoplasmic protein, based on the topological model previously described (Saldías et al. 2008), fusion of TrxA to the N-terminus of WbaP CT should result in localization of TrxA to the periplasm. However, rapid folding of TrxA after translation prevents it from crossing the plasma membrane (Huber et al. 2005).In this protocol, a fusion of trxA to any desired gene is constructed and the resulting fusion protein is expressed in an appropriate host strain. Additional protocols describe E. coli cell lysis and fractionation, osmotic release of thioredoxin fusion proteins from the E. coli cytoplasm, and heat treatment to purify some thioredoxin fusion ... Two thioredoxins have been described in Escherichia coli, TrxA and Trx2. Both thioredoxins are capable of reducing disulfide bonds using a conserved pair of cysteine residues present in a WCGPC motif. A number of unique structural and regulatory features distinguish the Trx2 subfamily from the much larger TrxA family. The Trx2 subfamily has an additional N-terminal domain of ± 30 residues ... TRxA accomplishes this by providing academic researchers with funding and guidance to define optimal strategies to advance cutting-edge new therapeutics from the lab to clinical trials and, ultimately, patient care.
