The resultant phage has a ...Oct 1, 2021 · Results Bioinformatics analysis showed that felixounoviruses encode DNA polymerase, which is homologous to the T7 DNAP. We found that the Escherichia coli thioredoxin A (TrxA) in vitro interacts with the predicted DNAP of Alf5 phage (gp096) and enhances its activity. 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 …SmaI can be used at 37°C for brief incubations. Efficient cleavage requires at least two copies of the SacII recognition sequence. Bacterial vector for expressing NusA fusion proteins.
