Bacterial enhancer binding proteins (bEBPs) are transcriptional activators that assemble as
hexameric rings in their active forms and utilize ATP hydrolysis to remodel the conformation …

The bacterial phage shock protein (Psp) response functions to help cells manage the
impacts of agents impairing cell membrane function. The system has relevance to …

SUMMARY ς54 has several features that distinguish it from other sigma factors in
Escherichia coli: it is not homologous to other ς subunits, ς54-dependent expression …

Nucleases containing programmable DNA-binding domains can alter the genomes of model
organisms and have the potential to become human therapeutics. Here we present DNA …

This map is an update of the edition 9 map by Berlyn et al.(MKB Berlyn, KB Low, and KE

The phage shock protein (Psp) F regulon response in Escherichia coli is thought to be
induced by impaired inner membrane integrity and an associated decrease in proton motive …

Alternative σ-factors of bacteria bind core RNA polymerase to program the specific promoter
selectivity of the holoenzyme. Signal-responsive changes in the availability of different σ …

Initiation of transcription is a major point of transcriptional regulation and invariably involves
the transition from a closed to an open RNA polymerase (RNAP) promoter complex. In the …

The phage shock protein operon (pspABCDE) of Escherichia coli is strongly up-regulated in
response to overexpression of the filamentous phage secretin protein IV (pIV) and by many …

ABSTRACT The Gram-negative bacterium Vibrio cholerae is the etiological agent of cholera,
a disease characterized by the release of high volumes of watery diarrhea. Many medically …
