The promoter of the threonine operon was joined to the structural genes of the lac operon in Escherichia coli K 12. The synthesis of beta-galactosidase was thus repressed by threonine plus isoleucine in the fusion strains. To isolate mutations which affect the expression of the threonine operon, alt

The bifunctional enzyme imidazoleglycerolphosphate dehydratase and histidinolphosphate phosphatase is encoded by the hisB gene. The fourth gene of the histidine operon, hisB, was cloned and mapped on a 2,300 base pair DNA fragment. In the present study we report the complete nucleotide sequence of t
The regulatory region of the Escherichia coli uvrC gene has been analysed by the subcloning of appropriate restriction fragments into the promoter probe vector pPV502. A series of plasmids carrying operon fusions to the gene for chloramphenicol acetyltransferase (cat) has been constructed. Three pro
