... a promoter where RNA polymerase binds and a repressor gene (trp R) which synthesizes a specific protein ... The protein that is synthesized by trp R then binds to the operator which then causes the transcription to be blocked ... In the lac operon, allolactose binds to the repressor protein, allowing gene transcription, while in the trp operon, tryptophan binds to the repressor protein effectively blocking gene transcription ...
Operon - Regulation
... Negative control involves the binding of a repressor to the operator to prevent transcription ... In negative inducible operons, a regulatory repressor protein is normally bound to the operator, which prevents the transcription of the genes on the ... If an inducer molecule is present, it binds to the repressor and changes its conformation so that it is unable to bind to the operator ...
