<P> The trp operon is an operon -- a group of genes that is used , or transcribed , together -- that codes for the components for production of tryptophan . The trp operon is present in many bacteria , but was first characterized in Escherichia coli . The operon is regulated so that when tryptophan is present in the environment , the genes for tryptophan synthesis are not expressed . It was an important experimental system for learning about gene regulation , and is commonly used to teach gene regulation . </P>
