Quizplus · Accepted Answer

Tryptophan acts as a corepressor in the regulation of the trp operon. When tryptophan is present in excess, it binds to the repressor protein and activates it, causing the repressor to bind to the operator region of the trp operon and prevent transcription. This is an example of negative regulation, as the presence of tryptophan inhibits gene expression.
