WebSchéma explicatif de l'opéron lactose. L' opéron lactose, ou opéron lac est un opéron nécessaire au transport et au métabolisme du lactose chez Escherichia coli, ainsi que d'autres bactéries de la flore intestinale. L'opéron lactose est composé de trois gènes structurels : lacZ, lacY et lacA. Il est régulé par plusieurs facteurs ... WebThermo Scientific IPTG (isopropyl-beta-D-thiogalactopyranoside) is a highly stable synthetic analog of lactose. It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. IPTG is used to induce expression of cloned genes under control of the lac operon.
