Question

Quizplus · Accepted Answer

Effector molecules are substances that can bind at a specific site on a regulator protein, thereby controlling whether or not the regulator can bind to the appropriate site on a target molecule. Activator and derepressor molecules affect the binding affinity of a regulator for its target, but they do not directly control whether or not the regulator can bind to the site.
