The lactose repressor turns the bacterial genes for lactose metabolism on and off. This system has served as a blueprint for the study of both eukaryotic and prokaryotic gene regulation for decades. In this issue of Science , the crystal structure of the whole lactose repressor in a complex with DNA and its inducer is reported. In her Perspective, K. Matthews discusses the significance of this landmark event.
