The lac operon found in some bacteria is one of the most well-known of these. The lac operon controls the production of the enzyme lactase (also called β-galactosidase) and two other structural proteins. Lactase breaks down the substrate lactose so that it can be used as an energy source in the bacterial cell.

The Trp operon plays a crucial role in tryptophan production, an essential amino acid. In E. Coli, the operon consists of genes and regulatory DNA sequences, including the promoter and operator. Tryptophan acts as a co-repressor, binding to the Trp repressor and inhibiting transcription when abundant.
