WebWhat happens as tryptophan levels go down? However, when tryptophan availability is low, the switch controlling the operon is turned on, transcription is initiated, the genes are expressed, and tryptophan is synthesized. ...When tryptophan is absent, the repressor protein does not bind to the operator and the genes are transcribed. 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… WebMar 20, 2024 · The regulation by repression involves a repressor and the repressor of the tryptophan operon is the repressor tryptophan.
