Abstract: | Abstract A specialized transducing phage λ carrying the structural gene for β-cystathionase ( metC ) of Escherichia coli was isolated. The phage carries a 21-kb fragment of the E. coli K-12 chromosome, and its structure was analyzed using restriction enzymes. The metC gene was recloned into resistance plasmid pBR322, using Eco RI or Hin dIII. The information for the metC gene is contained in a 1.3-kb fragment, which shows a high degree of homology with representative strains of all tribes of Enterobacteriaceae. |
