PspA promoter

pspA promotor is a sigma-54 (σ-54) regulated activator dependent promotor. sigm54-RNA holoenzyme (σ-54 RNAP) forms an inactive transcriptional initiation complex on this promotor, which can be activated in E. coli by the bacterial enhancer-binding protein PspF (BBa_K3071006). PspF functions by binding to the upstream activation sequences (UAS) near the promoter and contacting the promotor-bound σ-54 RNAP via DNA looping stabilized by the binding of integration host factor (IHF). Previous research has demonstrated the property of pspF-dependent and enhancer-specific transcription activation of pspA promotor.
