A fully recombinant system for activator-dependent archaeal transcription.
The core components of the archaeal transcription apparatus closely resemble those of eukaryotic RNA polymerase II, while the DNA-binding transcriptional regulators are predominantly of bacterial type. Here we report the construction of an entirely recombinant system for positively regulated archaeal transcription. By omitting individual subunits, or sets of subunits, from the in vitro assembly of the 12-subunit RNA polymerase from the hyperthermophile Methanocaldococcus jannaschii, we describe a functional dissection of this RNA polymerase II-like enzyme, and its interactions with the general transcription factor TFE, as well as with the transcriptional activator Ptr2.
