Iptg induces lac operon
WebThe lac repressor's conformation is altered by ONPF binding, preventing it from releasing from the operator DNA sequence even in the presence of an inducer like lactose or IPTG. As a result, the lac operon continues to be repressed since RNA polymerase is unable to transcribe its genes. In conclusion, IPTG and ONPF both interact with the lac ... WebDescription. As a galactose mimetic, IPTG can induce the lac operon, so it is commonly used to induce protein expression. IPTG is usually used for colony selection together with X-Gal in blue/white screening. Synonyms. Isopropylthiogalactoside. Chemical Name. Isopropyl-beta-D-thiogalactopyranoside. Relevant Disease. Neurological Disorders.
