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 …

Gene transcription is carried out by RNA polymerase (RNAP) and requires the conversion of
the initial closed promoter complex, where DNA is double stranded, to a transcription …

Cellular RNA polymerase is a multi-subunit macromolecular assembly responsible for gene
transcription, a highly regulated process conserved from bacteria to humans. In bacteria …

Background Sigma-54 is a central regulator in many pathogenic bacteria and has been

The bacterial AAA+ enhancer-binding proteins (EBPs) HrpR and HrpS (HrpRS) of
Pseudomonas syringae (Ps) activate σ54-dependent transcription at the hrpL promoter; …

Gene transcription is a fundamental cellular process carried out by RNA polymerase (RNAP)
enzymes and is highly regulated through the action of gene regulatory complexes. Important …

Type VI secretion systems (T6SS) are bacteriophage-derived macromolecular machines
responsible for the release of at least two proteins in the milieu, which are thought to form an …
