In the case of the trp operon, the ligand tryptophan is required for the repressor to work (repressible negative regulation).
The operon operates by a negative repressible feedback mechanism. The repressor for the trp operon is produced upstream by the trpR gene, which is constitutively expressed at a low level. Synthesized trpR monomers associate into dimers. When tryptophan is present, these tryptophan repressor dimers bind to tryptophan, causing a change in the repressor conformation, allowing the re… WebOct 8, 2024 · Essentially Trytophan foods will help you sleep at night.
