Jun 28, 2017 · Abstract. 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. T1, T5, and ϕ80 recognize FhuA, a ferrichrome transporter of the E. coli outer membrane 41, as the receptor for phage DNA injection, while T7 adopts thioredoxin (TrxA) in the host cell as a ...As a feasibility test for GOTraP, we first examined whether it enriches tail proteins in E.coli lacking waaC and trxA (BW25113ΔtrxAΔwaaC).This host does not support T7 phage propagation due to lack of trxA and does not encode the T7 host receptor, lipopolysaccharide (LPS), because it lacks waaC, a gene required for LPS biosynthesis …

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.E. coli TrxA is a small cytoplasmic protein, which belongs to the thioredoxin family and has a broad in vivo specificity [43,44]. It has been shown that TrxA also …

Strategy IA consisted of phage growth on E. coli BW25113 ∆trxA, which lacks the thioredoxin gene. Since this gene is essential for phage replication, this host only allows the replication of phage genomes that have acquired a copy of the trxA gene. Unfortunately, PCR-detectability of the chimeric phage was lost over the first few rounds of ...Oct 16, 2019 · Although none of the trx or grx genes are directly controlled by OxyR or OhrR, expression of trxA and trxC is induced by tert-butyl hydroperoxide (t-BHP). We further show that the trxA and trxC genes respond to effects of glutathione (GSH) depletion rather than oxidation. These findings underscore the particular importance of Trx in the ... Sep 11, 2022 · Oenococcus oeni is the main microorganism that undergoes malolactic fermentation (MLF) in the winemaking industry due to its excellent adaptability to harsh wine environments. The start of MLF is often delayed or even fails, and low pH appears to be a crucial parameter. To study the function of the trxA gene in acid stress, a plasmid containing the trxA gene of O. oeni SD-2a was heterologously ... TrxA serves as a reducing substrate for the elongation factors G and Tu , suggesting that TrxA regulates the translational machinery in vivo. Other cellular processes that also appear to be regulated by TrxA are nitrogen fixation [ 29 ], glycogen synthesis [ 71 ], and the oxidative stress response [ 72 ].Since a trxA, trxC, grxA strain is not viable unless complemented by one of the three genes, we conclude that these three are the only (sufficiently expressed) proteins able to perform the disulfide-reductive functions essential for aerobic growth of E.coli. Furthermore, any one of these proteins expressed by itself is capable of supporting growth.A Δgor ΔtrxA double mutant (E. coli Δgor/trxA) is no longer able to reduce PAPS red.
