WebA repressible operon is a type of operon in which the transcription of the gene is repressed by the presence of a particular substance. It is regulated by a co-repressor i.e., mainly the end product of the metabolic pathway. Normally repressible operon is on but in the presence of the co-repressor the pathway becomes off. WebJul 7, 2024 · The tryptophan (trp) operon system is a type of repressible operon system. It was worked out by Jacob and Monod in 1953. …. When tryptophan is present, it binds the trp repressor and induces a conformational change in that protein, enabling it to bind the trp operator and prevent transcription (operon is repressed). Web(II) Repressible Operon (Tryptophan Operon and Arginine Operon): In this system, operon is usually on so that transcription occurs normally to synthesize enzymes. But operon can be switched off due to non-requirement of metabolite (Fig. 6.66 B). In tryptophan operon, formation of tryptophan (an amino acid) needs action of five enzymes in ... ctv weather girl michelle
