TLDR
In vitro transcription from pspA templates missing one or both of the UAS sites is reduced relative to wild-type templates, but is still appreciable; however, IHF acts as a negative regulator of pSPA transcription on these mutant templates.About:

The Role of Bacterial Enhancer Binding Proteins as Specialized Activators of σ54-Dependent Transcription
Matthew J. Bush,Ray Dixon +1 more
TL;DR: A comprehensive and detailed summary of recent advances in understanding of how bacterial enhancer binding proteins function is presented, paying particular attention to the importance of σ54 to the bacterial cell and its unique role in regulating transcription.

Metabolic Context and Possible Physiological Themes of ς54-Dependent Genes in Escherichia coli
TL;DR: The function and metabolic context of ς54-dependent genes primarily from a single organism, Escherichia coli, is considered, in which a reasonably complete list of �inth54- dependent genes has been identified by computer analysis combined with a DNA microarray analysis of nitrogen limitation-induced genes.

Managing membrane stress: the phage shock protein (Psp) response, from molecular mechanisms to physiology.
Nicolas Joly,Christoph Engl,Goran Jovanovic,Maxime Huvet,Tina Toni,Xia Sheng,Michael P. H. Stumpf,Martin Buck +7 more
TL;DR: Progress in understanding the mechanism of signal transduction by the membrane-bound Psp proteins, regulation of the psp gene-specific transcription activator and the cell biology of the Psp system is presented and discussed.
Journal ArticleDOI
Induction and Function of the Phage Shock Protein Extracytoplasmic Stress Response in Escherichia coli
TL;DR: It is demonstrated that PspA and PspG directly confront a variety of inducing stimuli by switching the cell to anaerobic respiration and fermentation and by down-regulating motility, thereby subtly adjusting and maintaining energy usage and pmf.

Function of a Bacterial Activator Protein that Binds to Transcriptional Enhancers
TL;DR: The nitrogen regulatory (NtrC) protein of enteric bacteria, which binds to sites that have the properties of transcriptional enhancers, is known to activate transcription by a form of RNA polymerase that contains the NtrA protein (sigma 54) as sigma factor (referred to as s Sigma 54-holoenzyme).
