To purify the TrxA, 6 × His -AnCra1 fusion protein, the extract soluble cell lysate was loaded onto a Ni–NTA-affinity column and eluted.

Since the trxA gene is located downstream of groEL and co-organized as an operon, it is possible that the control of trxA expression depends not only on the trxA-self promoter but also on the CtsR regulation system. Therefore, we examined transcriptional profiles under the treatment of heat shock and disulfide stress by Northern blot.Oct 29, 2020 · Aptamer H1 formed complex with His-TrxA only at the highest concentration of protein. In contrast, aptamer G1 did not show appreciable binding to its target GST protein in solution. These results again support the idea that aptamer affinity is often greatly influenced by the environmental factors and aptamers tend to perform the best in ...

Here, we cloned thioredoxin (trxA) and thioredoxin reductase (trxB) genes from B. choshinensis, and expressed the gene products in Escherichia coli with an …

Although TrxC is a thioredoxin secondary to TrxA in bacteria, deletion of trxC clearly suppressed the reduction in the transcript at a longer time point , implying that TrxC functions at least as an SqrR-induced polysulfide homeostasis system. Thus, although TrxA and TrxC play essentially redundant physiological roles, each also exerts specific ...

A, schematic of the trxA complementation assay. E. coli wildtype is able to grow on sulfate as the only sulfur source using 3'-phosphoadenosine-5'-phosphosulfate-reductase (PAPS red)-dependent sulfate assimilation. PAPS red itself is reduced by thioredoxin (TrxA) or one of the several glutaredoxins (GrxA, GrxB, and GrxC).

To understand how TrxA or YtpP could recognize the CoAlated substrate, we further studied the known B. subtilis TrxA structure in complex with a substrate (heterodimer) and the homodimeric disulfide bonded form of TrxA [52,56].

Mar 23, 2006 · capsulatus the trxA gene of R. sphaeroides shows a strong response to diamide. It increases about sixfold after addition of t-BOOH and two- to threefold after exposure to paraquat or H 2 O 2 (Li et al. 2003b). Apparently, glutathione depletion (induced by t-BOOH) is a stronger stimulus for trxA expression in R. sphaeroides than The undigested TrxA-omHD 6 may be ascribed to polymer forms, which may probably obturate the enzyme-recognized sequence. Based on the electronic point difference of rmHD 6 (pI 8.0) and other unwanted components (pI TrxA 4.67, pI TrxA-omHD6 5.90, pI enterokinase 5.20), a cation-exchange chromatography was applied to …While the trxA and trxB genes mapped to quite different sites in the chromosome, they are both linked to genes involved in excision repair of DNA damage after UV irradiation. Thus, trxA is located in a cluster of conserved genes, mutS2-trxA-uvrC, and trxB is located in a gene cluster just downstream of the uvrAB genes.The vector expressing peptide aptamers was inserted, pBiFc-VC155-TrxA-MCS-TrxA, to establish the aptamer library, pBiFc-VC155-TrxA-peptide-TrxA, and SOX2-VENUS1-172 fusion protein is expressed with pBiFc-VN173-SOX2.
