The TrxA-His6-EGFP also displays a very negative net charge at pH 7.5 (-13.5). This did not seem to impact significantly its binding to Davisil grade 643 silica particles, but its binding to Davisil grade 646 was much less efficient (Fig. S3). After purification, all proteins were active, as determine by the fluorescence of TrxA-His6 …
To check that selection with trxA was occurring and that chimeric phages could be obtained, phage mutants were created in a two-step manner using an in trans tail fibre. Following homologous recombination, the progeny was plated on E. coli BW25113 ∆trxA, containing a plasmid expressing wild-type tail fibres (pAG_30). The resultant phage has a ...Gloshedobin, a thrombin-like enzyme from the venom of Gloydius shedaoensis, is usually produced as inclusion bodies in Escherichia coli cell.

The results showed that the NusA was the most efficient fusion partner to improve the ...A nucleotide sequence for TrxA-MCS-TrxA containing the enzyme recognition sites was designed and obtained after performing high-fidelity PCR, followed by inserting TrxA-MCS-TrxA DNA into pBiFc-VC155 for pBiFc-VC155-TrxA-MCS-TrxA construction, and an MCS was inserted into a protein scaffold to form a constrained structure.The gene upstream of trxA was annotated as uvrD (Atu0023), encoding DNA helicase, an important enzyme in DNA repair and replication. uvrD and trxA are transcribed in the same orientation and are separated by a 77-bp region containing the promoter of trxA. The folC-trxA-uvrD gene organization is conserved in several Alphaproteobacteria (dataJan 16, 2020 · Thioredoxin (TrxA), as a subunit of T7 DNA polymerase, is the obligatory host factor for T7 growth . In principle, recombinants that produce TrxA by itself can form the plagues on BW25113ΔtrxA lawns. Therefore, trxA represents a useful select marker for T7 mutant screening, which remarkably accelerates the process of identifying recombinants.

Thioredoxin 1 is a processivity factor for T7 RNA polymerase, and it is reported that T7 phage can bind and lyse a trxA deletion strain, though T7 phage propagation is ...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.
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]. TrxA has a central hydrophobic core with four β-strands, which are surrounded by alpha-helices (Figure S5A,B). It ...

Microbes employ the thioredoxin system to defend against oxidative stress and ensure correct disulfide bonding to maintain protein function. Listeria monocytogenes has been shown to encode a putative thioredoxin, TrxA, but its biological roles and underlying mechanisms remain unknown.Nov 30, 2023 · Dr. Maaike Everts, Executive Director of C-Path's TRxA, also shared her perspective on the collaboration, stating, "Drug discovery and development is a team sport; many types of expertise, funding ... The primary function of thioredoxin 1 (TrxA) is to maintain the redox balance in living cells, including eukaryotes and prokaryotes. It is maintained in a reduced state by thioredoxin reductase in a reaction that consumes NADPH. By reducing the disulfide bonds, thioredoxin helps biomolecules maintain their native structure.
