Isolation and characterization of frameshift mutations in the lac operon

Journal of Molecular Biology, 1970
Abstract A set of lac − mutations has been isolated in cells of Escherichia coli after mutagenesis with ICR-191D, an acridine half-mustard known to cause frameshifts in bacteria. The mutations in the β-galactosidase gene ( z ) were studied and shown to have properties consistent with their assignment to the frameshift class: they are revertible ...

Cost-Benefit Tradeoffs in Engineered lac Operons

Science, 2012
Accounting for Lac When Escherichia coli expresses the lac operon, it needs to balance the potential increase in growth rate conferred through having the encoded proteins (which help it to take up and metabolize lactose) with the potential ...

The catabolite repression gene of the Lac operon in Escherichia coli

Journal of Molecular Biology, 1967
A new gene, CR, has been shown to participate in the control of transcription of the lac operon. A mutation in the CR gene leads to insensitivity to catabolite repression of the lac operon. No other changes could be found to result from the mutation. The CR gene appears to map genetically distant from the lac genes and near the tryptophan locus.
