WebIPTG or Isopropyl β-D-1-thiogalactopyranoside is a molecular analog of allolactose, which removes a repressor from the lac operon to induce gene expression. Allolactose is an isomer of lactose, formed when lactose enters cells. It acts as an inducer to initiate the transcription of genes in the lac operon. Web29 sep. 2024 · An inducer, a third type of regulatory molecule, is a small molecule that either activates or represses transcription by interacting with a repressor or an activator. In prokaryotes, there are examples of operons whose gene products are required rather consistently and whose expression, therefore, is unregulated.
