Tryptophan gene regulation
WebTrp Operon. -both the tryptophan and lactose operons are subject to negative control. --the repressor gene is not near the operon. -the repressor is made in the INACTIVE transformation, which is the opposite of the lactose repressor synthesized in the ACTIVE conformation. --tryptophan acts as a co-repressor which activates the repressor.

WebSo the trip optima Ron or the tryptophan opteron pretty much is responsible for encoding genes that synthesize and process the amino acid tryptophan. And so that means that if … WebMutations which knocked out the trp R (repressor) gene still showed some regulation of the trp operon (these mutants were not fully induced/repressed by tryptophan). The total range of trp operon regulation is about 700 X (on/off). When the trp repressor was knocked out, one still got about 10 X regulation by the absence or presence of trp.
