It has its own promoter (PI). A gene cluster, including promoter and any regulatory DNA sequences is called an operon, for example, the Lac operon. In this case, transcription from the operon is induced in response to a molecular signal-i.e. the presence of lactose, or allolactose.
Maxwell House Coffee's successful slogan, Good to the last drop was historically credited to the 26th President of the United States, Theodore Roosevelt. The folklore claims that during Roosevelt's visit in Nashville in 1907, he was served Maxwell House coffee. So impressed with the coffee, the president apparently said the famous words.
