Lactose operon repressor
EN
The lactose operon repressor is a DNA binding protein that functions to regulate the expression of the Lac operon.
In the absence of lactose it inhibits the expression of the genes lacZ-lacY-lacA which code for the lactose-degrading enzymes of the operon by binding to the operator region of the Lac operon, thus hindering RNA polymerase from binding to the Lac promoter.
The repressor is inactivated by lactose which binds to the repressor. This causes a confomational change that prevents it from binding to the operator region.
