Methanobacterium thermoautotrophicum RNA polymerase and transcription in vitro.
RNA polymerase (RNAP) purified from Methanobacterium thermoautotrophicum DeltaH has been shown to initiate transcription accurately in vitro from the hmtB archaeal histone promoter with either native or recombinant forms of the M. thermoautotrophicum TATA-binding protein and transcription factor TFB. Efforts to obtain transcription initiation from hydrogen-regulated methane gene promoters were, however, unsuccessful. Two previously unrecognized archaeal RNAP subunits have been identified, and complex formation by the M. thermoautotrophicum RNAP and TFB has been demonstrated.
