This plasmid is available through Addgene.The trxA::Km mutant exhibited a drastic decrease in the mutant/wild-type ratio, implying that there was strong attenuation of virulence (Fig. 6A and B). This experiment was repeated twice with the trxA::Km mutant, and similar results were obtained, which verified the importance of TrxA for in vivo virulence.The trxA gene is located at 84 min on the E. coli linkage map, between uvrE and metE; trxA is 34% co-transducible with metE. The DNA polymerase induced by bacteriophage T7 is composed of a phage-specified subunit, the gene 5 protein, and a host-specified subunit, the 12,000 daltoThe Escherichia coli K-12 trxA gene, the gene encoding thioredoxin, has been cloned and sequenced. The DNA sequence includes 280 base pairs upstream and 46 base pairs downstream of the coding region.
