The lactose operon (lac operon) is an operon required for the transport and metabolism of lactose in E. coli and many other enteric bacteria. Although...

classically defined in the lac operon as a segment between the promoter and the genes of the operon. The main operator (O1) in the lac operon is located slightly...

the lac operon. The gene lacI is situated immediately upstream of lacZYA but is transcribed from a lacI promoter. The lacI gene synthesizes LacI repressor...

used as an example of gene regulation in bacteria alongside the lac operon. trp operon contains five structural genes. The roles of their products are:...

Regulation of acupuncture Lac operon, abbreviated Lac, operon controlling the metabolism of lactose in bacteria such as E. coli Lac Viet, the ancient people...

binding base-specifically to the major groove of the operator region of the lac operon, with base contacts also made by residues of symmetry-related alpha helices...

normally used in molecular biology to induce the lac operon. Inducer Lac operon § Regulation by allolactose Lac repressor allolactose at the U.S. National Library...

lac operon is repressed. This is because glucose actively prevents the induction of lacZYA. In the ara operon (also known as the ara or araBAD operon)...

transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator. Like allolactose...
