title: Genetic and physical analysis of the thioredoxin (trxA) gene of Escherichia coli K-12.
abstract: The trxA gene of Escherichia coli K-12 has been cloned into multicopy plasmids on DNA fragments of varying sizes. The smallest of these was a 1-kb fragment resulting from partial digestion with Sau3A (pBHK10). The complete nucleotide sequence of the trxA gene and its promoter was determined. Comparison of the DNA sequence with the published amino acid sequence revealed the inversion of two amino acid pairs and the possibility of a leader peptide 18 amino acids in length. Three-factor P1 transductional crosses and physical mapping experiments have determined a map order of ilv-trxA-uvrD-corA-metE.
