Trp operon (video) | Khan Academy
The Trp operon plays a crucial role in tryptophan production, an essential amino acid. In E. Coli, the operon consists of genes and regulatory DNA sequences, including the promoter and operator. Tryptophan acts as a co-repressor, binding to the Trp repressor and inhibiting transcription when abundant.

Khan Academy
Gene regulation in bacteria involves the control of gene expression to adapt to environmental changes and optimize cellular functions.
Operon trp - Khan Academy
O operon trp é regulado pelo repressor trp. Quando ligado ao triptofano, o repressor trp bloqueia a expressão do operon. A biossíntese do triptofano também é regulada pela atenuação (mecanismo baseado no acoplamento entre transcrição e tradução).
The lac operon - Khan Academy
To use lactose, the bacteria must express the lac operon genes, which encode key enzymes for lactose uptake and metabolism. To be as efficient as possible, E. coli should express the lac operon only when two conditions are met:

Operon TRP - Khan Academy
O operon trp é um operon bem estudado quando se trata de regulação gênica. Está envolvido na biossíntese do aminoácido triptofano.

在 E. coli 细菌中发现的 trp 操纵子是一组基因，它们编码了合成氨基酸色氨酸（tryptophan）所需的生物合成酶。 当色氨酸水平较低时， trp 操纵子被表达（“打开”），较高时表达则被抑制（“关闭”）。
El operón trp - Khan Academy
El operón trp es regulado por el represor trp. Cuando se une a triptófano, el represor trp bloquea la expresión del operón. La biosíntesis del triptófano también está regulada por la atenuación (un mecanismo basado en el acoplamiento de transcripción y traducción).
