T7 promoter wiki
WebThe dsDNA is a fully duplex promoter that contains the T7 ϕ10 promoter consensus sequence from -21 to +19 and initiates RNA synthesis at +1 with the sequence GGG. The p … WebThe T7 promoter, responsible for the transcription of the Ll.LtrB group II intron, was replaced with a clostridial promoter region, namely of the beta-2 toxin gene (cpb2) from a C. perfringens type A isolate. The final vector (pJIR750ai) was, after retargeting, shown to be able to successfully insert into the alpha toxin targeted gene plc.
