Few proteins have had such a strong impact on a field as the lac repressor and λ repressor have had in Molecular Biology In bacteria, the genes required for lactose utilization are negatively regulated; the lac repressor binds to an upstream operator blocking transcription of the enzymes necessary for lactose utilization. A similar switch regulates the virus life cycle; λ repressor binds to an operator site and blocks transcription of the phage genes necessary for lytic development. It is now 50 years since Jacob and Monod first proposed a model for gene regulation, which survives essentially unchanged in contemporary textbooks. This model provides a cogent depiction of how a set of genes can be coordinately transcribed in response to environmental conditions and regulates metabolic events in the cell. A historical perspective is presented that illustrates the role these two repressor molecules played and their contribution to our understanding of gene regulation.
