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 mechanistic insights have been gained from structural studies on mult

Bacterial enhancer binding proteins (bEBPs) are specialized transcriptional activators that assemble as hexameric rings in their active forms and utilize ATP hydrolysis to remodel the conformation of RNA polymerase containing the alternative sigma fa

The bacterial activator protein NorR binds to enhancer-like elements, upstream of the promoter site, and activates sigma(54)-dependent transcription of genes that encode nitric oxide detoxifying enzymes (NorVW), in response to NO stress. Unique to th

Molecular machines belonging to the AAA+ superfamily of ATPases use NTP hydrolysis to remodel their versatile substrates. The presence of an insertion sequence defines the major phylogenetic pre-sensor I insertion (pre-SIi) AAA+ superclade. In the ba

σ(54)-dependent transcription controls a wide range of stress-related genes in bacteria and is tightly regulated. In contrast to σ(70), the σ(54)-RNA polymerase holoenzyme forms a stable closed complex at the promoter site that rarely isomerises i

A flavorubredoxin and its associated oxidoreductase (encoded by norV and norW respectively) detoxify NO (nitric oxide) to form N2O (nitrous oxide) under anaerobic conditions in Escherichia coli. Transcription of the norVW genes is activated in respon
