Single-round promoter competition experiment with B. japonicum RNA polymerase core enzyme and holoenzyme reconstituted with purified RpoH proteins. The B. japonicum dnaKJ, groESL1, hspA rpoH1, and rrn promoters were provided at equimolar concentrations (10 nM each). The corresponding transcripts are indicated. The vector-encoded reference transcript (ref) was produced only in the presence of the holoenzyme.
