MeSH definition : Bacterial repressor proteins that bind to the LAC OPERON and thereby prevent the synthesis
of proteins involved in catabolism of LACTOSE. When lactose levels are high lac repressors
undergo an allosteric change that causes their release from the DNA and the resumption
of lac operon transcription.;
