The tryptophan repressor blocks the transcription and expression of the genes, thereby creating negative feedback regulation of the tryptophan synthesis process.
en.wikipedia.org So high levels of tryptophan prevent tryptophan synthesis through a negative feedback loop and, when the cell's tryptophan levels are reduced, transcription from the trp operon resumes.
en.wikipedia.org The operon is regulated so that when tryptophan is present in the environment, the genes for tryptophan synthesis are not expressed.
en.wikipedia.org However, when tryptophan is already available to the cell, these genes for tryptophan synthesis are no longer needed.
en.wikipedia.org In bacteria that synthesize tryptophan, high cellular levels of this amino acid activate a repressor protein, which binds to the trp operon.
