The NTRC protein of enteric bacteria is an enhancer-binding protein that activates transcription in response to limitation of combined nitrogen. NTRC activates transcription by catalyzing formation of open complexes by RNA polymerase (θ54holoenzyme form) in an ATP-dependent reaction. To catalyze open complex formation, NTRC must be phosphorylated. We show that phosphorylated NTRC has an ATPase activity, and we present biochemical and genetic evidence that NTRC must hydrolyze ATP to catalyze open complex formation. It is likely that all activators of θ54holoenzyme have an ATPase activity.
