Required for the transport and metabolism of lactose in Escherichia Coli (E. coli).The lactose operon or lac operon consists of three structural genes namely lacZ, lacY, and lacA that encode ...

The operon is regulated by Lac repressor, the product of the lacI gene, which is transcribed from its own promoter (PI). The repressor inhibits transcription by binding to the lac operator (O).

Nature Reviews Microbiology - cAMP does not have an important role in carbon catabolite repression of the Escherichia coli lac operon ...

A new strain of E. coli is to blame for multiple outbreaks of foodborne illness, according to new research published by the Centers for Disease Control and Prevention (CDC). Researchers found that … ...

To further test the idea, Igoshin and Ray examined the operon organization of the E. coli genome. They found operons were frequent when the type of interaction that they encoded worked to suppress ...
