[[1msw]] is a 4 chain structure | == Function == | ||
[https://www.uniprot.org/uniprot/RPOL_BPT7 RPOL_BPT7] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Responsible for the transcription of the late genes of T7. It is rifampicin-resistant. It recognizes a specific promoter sequence, unwinds the double-stranded RNA to expose the coding strand for templating, initiates transcription preferentially with a purine. | |||
