Trp operon. 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.
