In the case of the trp operon, when concentrations of tryptophan in the cell are high, some tryptophan molecules bind as a corepressor to the repressor protein. ○ This activates the repressor and turns the operon off. At low levels of tryptophan, most of the repressors are inactive, and the oper ...
