regulon Biol.|ˈrɛgjʊlɒn|
[f. regulate v. + -on1.]
A unit comprising all the genetic material whose transcription is regulated by a single inducer or repressor.
1964Maas & Clark in Jrnl. Molecular Biol. VIII. 365 The term regulon is proposed to describe such a system in which the production of all enzymes can be controlled by a single repressor substance. Two types of regulons can be distinguished, those in which the structural genes for the enzymes are adjacent to each other (histidine, tryptophan) and which thus consist of single operons, and those in which they are not (arginine) and which thus consist of several operons. 1976Ann. Rev. Microbiol. XXX. 549 Because a single repressor regulates the specific expression of these operons with G3P as the inducer, the system has been referred to as the glp (for glycerophosphate) regulon. 1978Jrnl.
