Regulatory proteins bind to repressor

trp operon and lac operon are two different systems: trp operon is repressible while lac operon is inducible. Their common feature is that both have effector molecules that binds with repressor proteins, but the interactions yield different results. In an inducible system like lac operon, the interaction was initiated so that the repressor protein cannot bind to the operator, while in a repressible system like trp operon, the interaction was made so that the repressor protein can bind to the operator.
