Mitomycin C-induced expression of trpA of Salmonella typhimurium inserted into the plasmid ColE1.

EcoRI endonuclease digestion of the deoxyribonucleic acid of a phi80 transducing phage carrying the entire tryptophan (trp) operon of Salmonella typhimurium (phi80 S.t.trpE-A) yielded a 4.3 X 10(6)-dalton fragment containing intact trpE, trpD, and trpC and a 3.35 X 10(6)-dalton fragment containing intact trpA. The trpA fragment inserted into EcoRI-cleaved plasmids ColE1 and CR1 was expressed regardless of its orientation of insertion. Mitomycin C, a compound that induces colicin E1 production in ColE1-containing bacteria, stimulated tryptophan synthetase alpha production in cells containing ColE1-TRPA plasmids with the trpA fragment inserted in one orientation but not the other. We conclude that in the inducible plasmids trpA can be expressed from the colicin E1 promoter.[1]
