乳糖操縱子(英語：lac operon) 是一個在大腸桿菌及其他腸道菌群內負責乳糖的運輸及代謝的誘導操縱子。儘管葡萄糖是大多數細菌的首選碳源，但是當葡萄糖無法通過β-半乳 ...

乳糖存在時，誘導物(inducer，即乳糖(lactose))與抑制子結合à使抑制子構型改變(為inactive)而不與操作子結合à在啟動子上的RNA聚合酶(RNA polymerase)即可經過操作子至 ...

The lac operon of E. coli contains genes involved in lactose metabolism. It's expressed only when lactose is present and glucose is absent.

The lactose operon (lac operon) is an operon required for the transport and metabolism of lactose in E. coli and many other enteric bacteria.

The lac operon is an inducible operon that utilizes lactose as an energy source and is activated when glucose is low, and lactose is present. The presence of ...

“Lac operon is an operon or a group of genes with a single promoter that encode genes for the transport and metabolism of lactose in E.coli and other bacteria.” ...
