Activation of prokaryotic transcription through arbitrary protein-protein contacts.

Abstract excerpt

Many transcriptional activators in prokaryotes are known to bind near a promoter and contact RNA polymerase, but it is not clear whether a protein-protein contact between an activator and RNA polymerase is enough to activate gene transcription. Here we show that contact between a DNA-bound protein and a heterologous protein domain fused to RNA polymerase can elicit transcriptional activation; moreover, the...
